For each beam shown in the associated figure, compute the deflection at the element nodes. The modulus of elasticity is E = 10 × 106 psi and the cross section is as shown in each figure. Also compute the maximum bending stress. Use the finite element method with the minimum number of elements for each case. 500 lb 200 lb 10 in. - 8 in. →←8 in. 400 in.-lb D₁ =1.5 in.
