Question

(a) 20° – 30°

(b) 30° – 40°

(c) 40° – 60°

(d) 60° – 80°

I have been asked this question during a job interview.

My question comes from V-Belts topic in chapter Belt, Rope and Chain Drives of Machine Kinematics

Answer 1

Right option is (b) 30° – 40°

Best explanation: The V-belts are made of fabric and cords moulded in rubber and covered with fabric and rubber. These belts are moulded to a trapezoidal shape and are made endless. These are particularly suitable for short drives. The included angle for the V-belt is usually from 30° to 40°.
