Machine Design A shaft is subjected to fluctuating loads for which the normal torque (T) and bending moment (M) are 1000 N-m and 500 N-m respectively. If the combined shock and fatigue factor for bending is 1.5 and combined shock and fatigue factor for torsion is 2, then the equivalent twisting moment for the shaft is 2050 N-m 2136 N-m 2000 N-m 2100 N-m 2050 N-m 2136 N-m 2000 N-m 2100 N-m ANSWER DOWNLOAD EXAMIANS APP

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 2 τ τ/2 τ 4 τ 2 τ τ/2 τ 4 τ ANSWER DOWNLOAD EXAMIANS APP
Machine Design If T₁ and T₂ are the tensions on the tight and slack sides of the belt respectively, and Tc is the centrifugal tension, then initial tension in the belt is equal to (T₁ + T₂ + Tc)/2 T₁ + T₂ + Tc (T₁ - T₂ + Tc)/2 T₁ - T₂ + Tc (T₁ + T₂ + Tc)/2 T₁ + T₂ + Tc (T₁ - T₂ + Tc)/2 T₁ - T₂ + Tc ANSWER DOWNLOAD EXAMIANS APP
