Cantilever steel rod is loaded by axial concentrated forces.
Given: l1=2,2l ; l2=1,9l ; l3=2,6l; F1=1,2P; F2=2,3P; F3 =-0,6P. Parameter of length l=30cm; cross section diameter: d=17mm. The rod is made of steel with yielding stress σY=270MPa; factor of safety n=1,8.
Find: allowable value of load parameter (in kN) from strength calculation
PA = ?
