Correct option is A
V-belts are ideal for short-distance applications (<1 meter) because of their high frictional grip, compact design, and ability to transmit significant power even over short distances. The trapezoidal cross-section of the V-belt increases the contact area with the pulley, reducing slippage and enhancing power transmission efficiency.
V-belt trapezoidal cross-section like transmit power or torque driving to driven component.
Applications:
· Used in automotive engines, industrial machines, and small appliances.
· Effective in compact setups where space is limited.
Advantages:
· High power transmission efficiency.
· Reduced vibration and noise.
· Requires minimal maintenance
