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 4 τ 2 τ τ/2 τ 4 τ 2 τ τ/2 ANSWER DOWNLOAD EXAMIANS APP
Machine Design Which of the following statement is wrong for a connecting rod? If Ixx > 4 Iyy, the buckling will occur about Y-axis If Ixx < 4 Iyy, the buckling will occur about X-axis The most suitable section for the connecting rod is T-section The connecting rod will be equally strong in buckling about X-axis and Y-axis, if Ixx = 4 Iyy If Ixx > 4 Iyy, the buckling will occur about Y-axis If Ixx < 4 Iyy, the buckling will occur about X-axis The most suitable section for the connecting rod is T-section The connecting rod will be equally strong in buckling about X-axis and Y-axis, if Ixx = 4 Iyy ANSWER DOWNLOAD EXAMIANS APP
