Transcribed Image Text:The beam AB has a negligible mass and thickness and is
subjected to a triangular distributed loading. It is
supported at one end by a pin and at the other end by a
post having a mass of 50 kg and negligible thickness.
(Figure 1)
Determine the minimum force P needed to move the post. The coefficients of static friction at B and C are uB = 0.4
and uc = 0.2, respectively. Take F = 880N/m.
Express your answer to three significant figures and include the appropriate units.
