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

When screw threads are to be used in a situation where power is being transmitted in one direction only, then the screw threads suitable for this will be

According to Indian standard specifications, 100 H6/g5 means that

The usual proportion for the width of key is (where d = Diameter of shaft or diameter of hole in the hub)
