A propeller shaft is required to transmit 45 kW power at 500 r.p.m. It is hollow shaft having inside diameter 0.6 times the outside diameter. It is made of plain carbon steel and the permissible shear stress is 84 N/mm2. The inner and outer diameters of the shaft are nearly
A shaft rotating at 150 rpm is subjected to a torque of 1500 N.m. Horse power transmitted by the shaft is
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
