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 2000 N-m 2136 N-m 2050 N-m 2100 N-m 2000 N-m 2136 N-m 2050 N-m 2100 N-m ANSWER DOWNLOAD EXAMIANS APP
