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

T₁= √(1.5x500) + (2x1000)² =2136 N-m

We know that equivalent twisting moment
T₁= √√(KXM)² + (K,XT)² Since T = 1000 N-m; M = 500 N-m; K=1.5 and K,= 2, therefore
T₁= √(1.5x500) + (2x1000)² =2136 N-m
