In the figure, torsional moments act on a bar system of abruptly changing cross-section made of the same material. Accordingly, calculate the value of the factor α so that the support responses are of the same magnitude in absolute value. What must the torsional moment=Mb be for the D-end to be zero?

TEST YOUR UNDERSTANDING! Problem 1 Four wires support the rigid members CD and AB. If a 500-lb load is applied at point I, determine the angle of tilt of AB and the displacement of point A. The members were originally horizontal, each wire has a cross-sectional area of 0.5 in² and E = 29 x 106 psi. (Taken from Hibbeler, 2015) Follow these questions for your solution: 1. Draw the FBDs of bar CD and bar AB. What are the forces in the wires? Problem 2 The horizontal rigid bar is supported by bars A and B and a pin support. If the system is loaded by P₁ and P2, what would be the vertical displacement of the point of application of P₁? Follow these questions for your solution: 1) Draw the FBDs needed. What is the normal force in bar A? in bar B? 2) Draw the deformation diagram. What compatibility equation would you use to determine the displacement of the point of application of P₁?
