(4) A vertical load P is applied on the handle A of the mechanism that is supported by a horizontal spring and two radial bearings at B and C. When the mechanism is in the position shown the spring is stretched 60 mm and end D is resting on the smooth surface. Determine the minimum load Pmin required to initiate rotation about the bearing axis BC and the magnitudes of the corresponding bearing reactions. Ans: Pmin = 18 N, B=30.8 N, C=29.7 N k = 900 N/m 55 mm 165 mm B 90 55 mm mm 135 mm D 135 40 mm mm 45 mm 45 mm
