4. Determine the slope and deflection at point A of the simply supported beam. It is given that the modulus of elasticity, E, is 29,000 ksi and the moment of inertia, I, is 400 in4. Solve the problem using moment-area theorems. Also, plot the shear, moment and deformed shape diagrams using RISA (be sure to use correct geometric and material properties). Compare your hand calculations to those obtained using RISA and discuss.
