The most efficient operating angle for a certain conveyor be

The most efficient operating angle for a certain conveyor belt is 31 degree If the parts must be moved a vertical distance of 16 ft, what length of conveyor is needed? Round to the nearest tenth.

Solution

from fig, Perpendicular / hypotenuse = sin31

16 ft / L = sin31

L (length) = 16/ sin31

L = 31 ft
