Subtopic: Measurement of force, stress, torque, speed, displacement and acceleration on machine elements – shafts, couplings, keys, bearings and knuckle joints
Question Statement:
A rigid flange coupling connecting two collinear shafts uses bolts fitted in reamed holes designed to transmit torque through:
Options:
(A) Transverse shear of the bolts
(B) Tensile elongation of the hub
(C) Centrifugal expansion of the rim
(D) Bending of the keyway
Answer Key:
A
Step-by-Step Solution & Explanation
Fitted bolts in flange couplings transmit torque directly via transverse shear across the flange mating interface.
