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 τ τ/2 4 τ τ 2 τ τ/2 4 τ ANSWER DOWNLOAD EXAMIANS APP
Machine Design An elastic bar is fixed at the upper end and loaded at the lower end by a falling weight. The shock load produced can be reduced by Decreasing the cross-sectional area of the bar Increasing the length of bar All of these Decreasing the modulus of elasticity of the bar Decreasing the cross-sectional area of the bar Increasing the length of bar All of these Decreasing the modulus of elasticity of the bar ANSWER DOWNLOAD EXAMIANS APP
