Cantilever steel rod is loaded by axial concentrated forces.
Given: l1=2,5l ; l2=1,7l ; l3=2,6l; F1=-2,6P; F2=0,4P; F3 =0,3P. Parameter of length l=40cm; cross section proportion: b=1,6h; parameter of loading P=37kN. The rod is made of steel with yielding stress σY=330MPa; factor of safety n=1,9.
Find: the height (in mm) of cross section from strength calculation h = ?
