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 4 τ τ/2 τ 2 τ 4 τ τ/2 τ 2 τ ANSWER DOWNLOAD EXAMIANS APP
Machine Design Two shafts ‘A’ and ‘B’ under pure torsion are of identical length and identical weight and are made of the same material. The shaft ‘A’ is solid and the shaft ‘B’ is hollow. We can say that Both the shafts are equally good None of these Shaft B is better than shaft A Shaft A is better than shaft B Both the shafts are equally good None of these Shaft B is better than shaft A Shaft A is better than shaft B ANSWER DOWNLOAD EXAMIANS APP
