Q.I A rotary shaft carries distributed load of 250 w/m with a long 3m. The
shaft transmits 35 KW at 290 rpm. A shaft is simply supported shaft. The
max. shear stresses 56 MPa and the allowable Compression stress 45 MPa,
the safety factor is 1.5. Find the size of the shaft if it subjected to suddenly
applied load.
