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 2 τ τ 4 τ τ/2 2 τ τ 4 τ ANSWER DOWNLOAD EXAMIANS APP
Machine Design Two helical springs of the same material and of equal circular cross-section, length and number of turns, but having radii 80 mm and 40 mm, kept concentrically (smaller radius spring within the larger radius spring), are compressed between two parallel planes with a load W. The inner spring will carry a load equal to W/2 8W/9 W/9 2W/3 W/2 8W/9 W/9 2W/3 ANSWER DOWNLOAD EXAMIANS APP
