Q$2.$ A horizontal steel beam with a moment of inertia of $60{10}^{6}m{m}^4$ carries a uniformly distributed load of $40$ kN over its length of $3$ m $.$ The beam is supported by three $1\mathrm{.}6$ m long vertical tie rods, one at each end and one in the middle. The diameter of each of the end rods is $20$ mm and that of the middle rod is $24$ mm $.$ Determine the deflection at the centre of the beam below the end points and the stress in each of the rod. $E=205$GPa
