8 Write down the name of the gear:(a)The teeth are at an angle to the shaft and the resulting teeth are longer than the teeth of spur gear of equivalent pitch diameter and it can carry more load than spur gear. It can be used to transmit power on non parallel and even perpendicular shafts.(b)These gears are used when high gear ratio is desired or again the shafts are perpendicular to each other.
