Two shafts are joined by friction welding. Rpm of rotating shaft is 6000 rpm. Pressure applied during welding is 60 MPa. Both shaft are made of same material and have 100 mm diameter. Calculate the total power required (kW) for welding process. [coefficient of friction = 0.65]
Assume that net frictional force acts at periphery of shaft.Enter numerical value using the virtual keypad. Round off where necessary.
