we can say, this is the perpendicular distance or the perpendicular component of force along the distance, either way. but i think we all know about this. let's suppose this kid goes home and someone takes his place. and it's a great, big, heavy set kid. can a heavy set kid play with a little skinny kid on the same seesaw? yeah. and you all know from experience, yes. a heavy kid can do it. and what the heavy kid does-- the heavy kid sits in here and the kids can still play. the kids can still play because who is providing the larger torque? the heavy kid or the light kid? check your neighbor. watch out for trick questions like this. who's providing the larger torque? check. how many people say, the larger kid is providing the same torque, that's why it balances. yay. see? the larger kid is pulling down with more force, but through less distance. so there's a greater force, but a lesser distance and if this equals that, they balance and it's okay. let's suppose the large kid is very, very obnoxious and this kid says i ain't gonna play with you anymore. can the large kid play with himself o

and everywhere here, note how the force is pulling, always perpendicular and if it's pulling perpendicular, then there's no component along the alley. so once you've got it rolling, how is it gonna roll? steady, steady, steady, unless you mess with it, okay? so let's suppose i get it rolling in a certain speed and let's suppose i cut part of the alleyway here, play a trick on it. here it comes, i'm rolling it, maybe like 4 kilometers per second, that's pretty fast. here we go. later on, come to the edgeway, crash into the ground. roll it faster. crash into the ground over there. roll it faster. boom, still crash into the ground. i wonder if there'd be a speed you could move it such that it would clear the gap. how many say, oh, no, there's no way to clear that gap? stand up, go on. see if you're sitting next to someone who can calculate in their mind, the reason in their mind or come up with the answer, how fast it gotta go to clear the gap? what'd be the answer, gang? past tense of eat... 8, 8 kilometers per second, you're gonna clear the gap. how about if you make the gap this big? gonna

we can use the 22 or 34 or 33 which runs perpendicular. however, to take that requires additional walking and a bus ride and a requires a transfer. what is the result for our riders especially the elderly atkins and the young. we believe it to be a serious inconvenience associated with changing buses especially at night. will the exciting 3 riders continue to be muni riders if you terminate their service. thank you >> thank you. >> i'm barbara and i live on jackson street and i'm following up with alex on say environmental impact of the plan. the goals set out to enhance accessibility and railways traffic time and improve reliability b will not be achieved. we estimate that half of the passengers about 2 hundred and 35 a day about 6 hundred people will be stranded and forced to use taxis. this adds 5 hundred miles of auto traffic and another 3 hundred and 25 cars and a taxis driving and parking downtown near union square. there are no benefits from the t e p instead we add 2 hundred and 25 metric tons of greenhouse gas. it's a negative imp

at the top of the stairs was always there ran perpendicular to the stairs. there was still no signs of the suspect or family members. officers made the decision they would have to clear the upstairs room by room. officer i. singh and hernandez went to the right. -- esein. as officer carrasco and heppler went left and saw a body lying prone at the end of the hallway. they saw the body was drenched in blood, and the victim was still breathing. based on his prior experience as a paramedic, officer carrasco knew they needed to be rescued immediately if there was to be any chance of the person surviving. officer carrasco told heppler i will pull her out. with complete disregard for his own safety, he ground the bleeding person by the feet and began to drag her to safety. it was later determined that the stick them was the suspect 73- year-old mother who had been stabbed through the neck. he pulled the woman passed officer heppler and a door opens at the end of the hallway. it was later determined to be the suspect's sister and ran hysterically across the hallway.

there's an ample of the header row, you see how they are turned perpendicular to each other, you can see the header rows in this one, see the brick going the other way about every 5 or 7 rows. deep set windows. here's a close up of one of those plates. a parapet wall is a clue that this building is an unreinforced building. which direction can that building go? right back out. this building, brick or wood? what are some of the clues? okay, what are the windows? they are deep set. there's a clue right there. deep set. deep set window, unreinforced masonry. can you see the metal plates? there is a metal plate right over there in the corner, there's another one over there. hard to see. also has a parapet on it. deep set windows. even though it has stucco on it, don't be

if it's 75% open to perpendicular view, basically what it means is you've got to go up to six feet, you need some sort of iron fence or something that is very transparent. and you can't mix and match. so you can't put a three foot solid fence and then put three more feet up to the six foot that's open because obviously you're at least 60% doed by virtue of the three feet. >> basically if you're building a fence over three feet high, you need to talk to the planning department or make sure the planning department code allows it. >> can you grow a hedge? >> the question, can you grow a hedge or plants? are plants regulated like fences? >> they're not. we don't regulate vegetation up to this point so you're free. >> that's a really good question. some people say i'm going to put a six foot fence in my backyard, it's exempt from permits and i'm going to plant bamboo that grows 15 feet high to block my neighbors looking into my hot tub or whatever it is. totally unregulated. vegetation is not regulated. knowing where your property line is is key to all of this. in this slide, we see a fence

been specific guidelines set up for playing sporting events parallel to the bay as opposed to perpendicular to the bay to address the students not being as close to the marina traffic as they could be if they were the opposite way. and all of our faculty has been over there. as i said, multiple times to really walk through that and understand what those expectations are and can at any time request additional support and parent volunteers should they feel the activity requires that. >> okay, great, thank you very much. >> if i may add, just clarify one point with park and rec. why we don't need to do more activation of open space immediately at the building. a question came up, why we use inside the building and little marina green. and it's that the open space around the palace of fine arts is a designated -- it's a nonstructured recreation area. since we are a group use, we do not interfere with public access. we actually go across. so, that's why we have a protocol, but that's why we choose -- that's r why we're going to those recreation areas. >> got it. commissioner moore. >> i just wan

shooting was very close and, even more importantly, if the trajectory of the shots were sort of perpendicularting that he was still advancing, that might lend some insight and credibility to why the officer shot. on the other hand, if he was far away, 10, 15 feet away or, god forbid, if there were shots put into the victim when he was on the ground, that's certainly going to suggest why they may have charged him so quickly with the crime. >> right. so obviously some unknowns, at least to us at this point. >> a lot. >> you just heard in that report, and something wore well aware of. look, some are saying african-american men are unfairly profiled in america. this is something charles barkley has said to me. he agreed with the verdict in your case, but he also has experienced that himself. it's something the president has talked about. it's reality. but do you think race played a role in this death? when you think about this situation, if a white guy is running down the road at a white cop, would he have been so quick to shoot? >> well, we have to look at what the cops are thinking about to beg

those who perpendicular such a horrible crime, whether israelis or others, should be held accountable to the international established mechanisms. not to the bully of the war, the policemen of the war represented by the american intelligence reports or false allegations coming from france or britain or saudi arabia or israel. we are in favor of a peaceful settlement of all of the con flibl flikts in the area and my country has been a victim of intrusion, interference in the domestic affairs by foreign intelligen intelligences. don't forget there is room of operation and jordan operating right now by the saudis and the pentagon and where they are training and instructing thousands of syrian mercenaries to invade syria from the south. the same thing exists in the north within the turkish territory. please, we have to look at the picture in its entirety and comprehensiveness. we are not training for wars or for agresing anybody else. we haven't declared war to the united states or any of our neighbors. >> mr. jaafari. >> we have a domestic crisis. yes, wrong doings happened in the past.

it's good to see you, profess perpendicular thanks for joining us. >> pleasure to be with you.come with you to nantucket tomorrow? >> that's andrew. i don't know, andrew. >> do you have a whale belt? >> look, i'll get whatever i need. >> there's a store that has one. so we all think it works, don't we, because of the brad pitt and -- who was was in that, that if you really delve hard into the data that you could predict the outcome for a season. do you think that is possible? >> delving hard into the data is used in a variety of ways. if you're talking about using it to assess talent, it can be successful in baseball. we talk about the impact of using data more frequently and more successfully on team performance and it does seem to have an effect. one of the issues for baseball, though, is that a lot of low hanging fruit has been picked. the simple concepts like on-base percentage that says walks is as important as well as hits. those were easy. and the front office has only had to pay $30,000 to hire somebody to tell them that. these days, they're doing much, much more so fes
