Subtopic: Design and selection of machine elements – gears, pulleys, chains and sprockets and belts
Question Statement:
In a flat belt drive, the condition for transmitting maximum power when allowable belt tension is $T_1$ and belt mass per unit length is $m$ occurs when the centrifugal tension $T_c$ equals:
Options:
(A) $T_1 / 3$
(B) $T_1 / 2$
(C) $2 T_1 / 3$
(D) $T_1 / 4$
Answer Key:
A
Step-by-Step Solution & Explanation
Maximum power transmission condition is $T_c = T_1 / 3$, corresponding to velocity $v = \sqrt{T_1 / (3m)}$.
