//solution
//given
f=100//N/mm^2
//let Ra and Rb be reaction at A and B
//taking moment about A
Rb={(35*750)+(25*150)}/950//kN
Ra=25+35-Rb//kN
//since maximum stress is taken into account, therfore maximum moment will be taken into calculations...

//Z=(pi/32)*d^3=0.0982*d^3
//100=Md/Z//because Md>Mc
