The bell-crank mechanism is in equilibrium for an applied load of P = 22,kN. Assume that a = 260 mm, b = 210 mm, and 8 = 57°. The pin at B has a diameter of d = 27 mm, and the bell crank has a thickness of t= 12 mm. Calculate the average shear stress in the pin at B. (1) C F₁

7 ft 5 ft The assembly shown above includes column AB, which has the following properties: Pinned (top and bottom) for buckling about x-axis Free at top and fixed at bottom for buckling about y-axis Circular cross-section with 8-inch diameter E = 10000 ksi Which of the following is closest to the critical buckling force of column AB? O Per = 269 kip O Per = 1080 kip O Per = 538 kip O Per = 135 kip

Required information Two solid steel shafts (G= 77.2 GPa) are connected to a coupling disk B and to fixed supports at A and C. Take T=1.4 KN-m. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 250 mm 200 mm 38 mm T 50 mm For the loading shown, determine the reaction at each support. The reaction at support A is N-m. The reaction at support C is N-m.
