Why are mountain roads generally made winding upwards rather than going straight up ? |
|
Answer» Solution :While going up a mountain the opposing force of friction ` F = mu R = mu mg COS 0 ` where `0` is angle of slope with HORIZONTAL To avoid skidding , `F` should be large `:. cos theta` should be large and hence `theta` must be small That is why mountain ROADS are generally made winding upwards. The road straight up would have LARGER slope . |
