Q.5) A crank mechanism is supported by a spring and bearings B and C. Bearing B does not exert any axial force. Bearing C exerts an axial force (force along the shaft) preventing the mechanism from sliding along axis BC. The spring is currently stretched 50 mm in the position shown and is aligned parallel to the y-axis. Note: bearings B and C are positioned along the x-axis and properly aligned so they do NOT exert any reaction moments on the mechanism. (a) Calculate the minimum force P required to initiate rotation about the hinge axis BC causing point D to lift off the block. Compute the reaction forces at B and C in this scenario. (b) If half the force found in part (a) is applied to the handle instead, determine the normal reaction force at point D.
