Cantilever rod is loaded by axial concentrated forces. Cross sections at each segment of the rod are circular.
Given: l1=1,6l; l2=1,1l; l3=1,2l; F1=1,8P; F2=2,7P; F3=3,8P. Parameter of length l=30cm, parameter of loading Р= 22кN.Diameters of circular cross sections: d1 =17мм, d2=14мм, d3=23мм.
Find: maximal absolute value of normal stress σ (in MPa).
