The mobile crane shown in figure 10.18 carries a $60\mathrm{kN}$ load. Calculate: a) The maximum stress in the horizontal arm $A$, made from rectangular tubing $100\mathrm{mm}$ deep and $75\mathrm{mm}$ wide and a wall thickness of $5\mathrm{mm}$. b) The stress on both sides of the vertical strut at section $x-x$. the outside and inside diameters of the strut is $140\mathrm{mm}$ and $125\mathrm{mm}$ respectively. c) The reaction at the wheels. d) The maximum stress in the horizontal axle $B$, with the outer and inner diameter of $80\mathrm{mm}$ and $60\mathrm{mm}$ respectively
