Compute the reactions at A, B, and C using the force method of analysis. Assume El is constant. You may use ay "Deflections" from the front cover of the book to solve. 3 k/ft C A 10 ft 10 ft B.

Please plot the FBDs that would allow you to find the smallest values of forces P1 and P2 required to keep the whole system in a state of equilibrium. Notes: The coefficient of static friction for all surfaces of contact is 0.3 The weight of the wedge B and C can be neglected The weight of block A is given in the picture You only need to plot the free body diagrams and do not need to actually solve for P1 and P2

The throttle-control lever OA rotates in the range 0 ≤ 0 ≤ 90°. An internal torsional return spring exerts a restoring moment about O given by M = K(0+1/4), where K = 300 N-mm/rad and 9 is in radians. Determine and plot as a function of the tension T required to make the net moment about O zero. The effects of the radius of the pulley at B are negligible. After you have completed the plot. answer the questions. Assume r = 50 mm, d = 100 mm. 45 d Answers: If 0 = 26%, the tension T = N If 0 = 48%, the tension T = N If 0 = 80%, the tension T = N i i i
