Answer to Question #261565 in Mechanical Engineering for Deepak

Question #261565

A simple flange coupling has to transmit 50 KW at 250 RPM. . Assume torque

to be 20 % more than the full load. Calculate (a) Shaft diameter (b) Key

Dimensions and (c) number & size of Bolts. The stresses are as under, For

Shaft & Key [σt] = 75 N/mm2, [] = 50 N/mm2,[σc] = 120 N/mm2 For Bolt

[]= 40 N/mm2
