Machine Design A closely coiled helical spring is acted upon by an axial force. The maximum shear stress developed in the spring is τ. The half of the length of the spring if cut off and the remaining spring is acted upon by the same axial force. The maximum shear stress in the spring in new condition will be τ/2 4 τ τ 2 τ τ/2 4 τ τ 2 τ ANSWER DOWNLOAD EXAMIANS APP
Machine Design When a circular beam of diameter d is subjected to a shear force F, the maximum shear stress induced will be 4F/ πd² 6F/ πd² 8F/ πd² 16F/ 3πd² 4F/ πd² 6F/ πd² 8F/ πd² 16F/ 3πd² ANSWER DOWNLOAD EXAMIANS APP
Machine Design A screw is said to be over hauling screw, if the Friction angle is more than helix angle Efficiency of screw is 100% Friction angle is equal to helix angle Friction angle is less than helix angle Friction angle is more than helix angle Efficiency of screw is 100% Friction angle is equal to helix angle Friction angle is less than helix angle ANSWER DOWNLOAD EXAMIANS APP
