A circular shaft of diameter d and length l is subjected to a torque T and a bending moment M. The ratio of maximum shear stress to bending stress is:
Hollow shafts are stronger than solid shafts having same weight because
Power transmitted by a shaft is given by expression _______ in kilowatts
A solid circular shaft needs to be designed to transmit a torque of 55 N m. if the allowable shear stress of the material is 280 N/mm2, find the diameter (in mm) of the shaft required to transmit the torque. (Assume, π = 22/7)
A circular shaft subjected to torsion undergoes a twist of 1° in length of 120 cm. If the maximum shear stress induced is limited to 1000 kg/cm2 and if modulus of rigidity G = 0.8 × 106 kg/cm2, then the radius of the shaft (in cm) should be
