1 (a)The bar shown in Figure 1(a) has a mass of 15 kg and is subjected to a couple moment of = (200M) N applied to the end of the bar. The spring has unstretched length of 0.4 m and remain in the vertical position due to roller guide at B. Note; Use your last three digit of matrix number to determine the value of force P as M = 70 Nm and a force P follows; Example of matrix number, CD180002 M= (0+0+2) = 2 Therefore, P = 200M = 200+2 = 202 N Draw the free body diagram of the bar to account for all the forces that act on (i) it. (ii) Determine the total work done by all the forces acting on the bar when it has rotated downward from 0 = 0° to 0 = 90°.

Problem 7. We have a line of two equal masses m connected by three springs with spring constants c₁ = 1, c₂ = 1, and c3 = S. Spring 1 is fixed at the top and spring 3 at the bottom, so xo = x3 = 0. (a) Find the stiffness matrix K in the equation Kx = f for the mass displacements. (b) Solve for the displacements x₁ and x2. (c) If the third spring constant S becomes very large or very small (S→∞ and S→ 0) what are the limiting values of the displacements x₁ and .x₂? (d) If the third spring constant S becomes very large or very small (S→∞ and S→ 0) what are the limiting values of the spring forces y1, y2, and y3? 91 www m 3-WW www C₁ X₁ "Xo = 0 C2₂ X2 C3 X3 = 0

1 m 1 m 1 m b B 30° 0.5 m 0.5 m b -1m 75 mm- 75 mm A 25 mm Section b-b Figure 3 (not to scale) A drum is suspended from the wooden frame ABC as shown in Figure 3. The mass of the drum is 20 kg. The frame ABC is supported by the 2 mm diameter, A-36 steel cable DB and by a pin support at A. You are required to: a Calculate all the internal forces acting at the cross section b-b and in cable BD. b Calculate the orientation of the plane and the magnitude of the maximum in- plane shear stress at point F, on section b-b, and represent this condition using a stress element. с Determine the factor of safety (F.S.) of the cable BD for this loading based on the maximum-distortion energy theory (von Mises).
