Driving Around a Bend Assignment Example | Topics and Well Written Essays - 1000 words

Driving Around a Bend - Assignment Example Higher is the speed and more is the angle of inclination. Many times, the turn is too sharp and/or the speed is too much to negotiate by the motorists and the vehicle skids causing fatal accidents. A car driver, unfortunately, cannot lean like a motorcyclist and therefore, he needs something else to help him negotiate a bend without skidding and that is banking on the road. In case of banking, there is an upward slope on the road from inner side towards the outer side of the circle. So the question is by what angle a motorcyclist should lean and also, what should be the angle of banking on the road near a bend to avoid skidding off a vehicle. These two are an essentially same problem and have been treated analytically in the subsequent section. Suddenly a bend comes on the road and he has to move along a circular arc. Moving along a circular arc requires centripetal acceleration and there must be a force to produce this acceleration. If the motorcycle goes on a horizontal circular path, this resultant force will also be horizontal. Let us consider a motorcycle of mass ‘m’ moving at a speed ‘v’ is negotiating a bend of radius ‘r’ and the road is horizontal. Therefore, the external forces acting on the vehicle are the following: As the road is horizontal, the normal reaction force ‘R’ is vertically upward. The only horizontal force that can act towards the center of the circular path is friction F. This is static friction and self-adjustable. The tires get a tendency to skid outward and the frictional force which opposes the skidding acts towards the center. Thus for the safe turn i.e. for the turn without skidding

A newspaper invites young people to write articles about television Coursework

A newspaper invites young people to write articles about television programmes they either loathe or love. Write the piece you would send to the newspaper - Coursework Example You can tell which series it is from the opening sequence. Actually I can tell what series it is from the extent of Chandler’s physical decline. He starts out quite fit and degenerates into an increasingly zombified, staring-eyed mess. Apparently he had to fight some addiction demons in real life. My theory is that working with this bunch gradually eroded his sanity. I only watch Friends because it provides the ideal opportunity for venting all my pent-up frustrations about life. For me this programme has all the charms of an emotional punchbag. I look at the smug, silly faces and enjoy an imaginary workout in the boxing ring with each one in turn. Except Chandler. Something worries me about Chandler. It is a fact that every viewer on the planet, unfortunately, has a soft spot for one of the six characters. It’s a kind of post-modern Rorschach test. The one you identify with reveals your true nature. I never did see the attraction of Friends, and even now, almost a decade after the last series gasped its way onto our screens, I don’t get it. I mean look at the stereotypical gender roles. The girls are all mad: Rachel is sex-mad, Monica is neurotic and has issues with food, issues with hygiene, issues with men, and a seriously weird relationship with her brother. And Phoebe. Well, Phoebe is the poster girl for cloud-cuckoo land. â€Å"Smelly cat, smelly cat†¦You smell like something dead†¦Ã¢â‚¬  What was that all about? I hope the producers are insured against all the law suits that are bound to follow from children thinking that this is acceptable behaviour in an adult human being. And the boys are not much better. Would you go out with any of them? The show has a formula that is repeated ad nauseam until finally the characters just show up on the set and the dialogue writes itself. In fact it is so predictable that a ten year old could write it and nobody would be any the wiser. Joey and Chandler have little boy-games in their flat, while Rachel
