I need the answer quickly
A shaft supported at the ends in ball bearings carries a straight tooth spur
gear at its mid span and is to transmit P kW at N Rm is shown in Fig. The
radius of the gear is R mm. The distances between the center line of bearings
and gear are L mm each. If the shaft is made of steel and the allowable shear
stress is 52 MPa, determine the diameter of the shaft if it's rotating and
suddenly applied load with minor shocks only.
