In the figure shown the blocks weighs 400 N each. It is held in the positionby a belt that passes over a fixed wheel , the belt being subjected to a horizontal force P at its end. The coefficient of friction between blocks and the inclined plane is 0.20 and 0.25 between the belt and the wheel. Calculate the ff:a. Magnitude of P in N when the block is at impending motion up the plane.b. Tension in the belt near the block in newtons.c. Contact angle between the wheels and the blocks.

The small roller on the upper end of the uniform rod rests against the vertical surface at A while the rounded end B rests on the platform which is slowly pivoted downward beginning at the horizontal position shown. For a coefficient of static friction , 0.37 at B, determine the angle of the platform at which slipping will occur. Neglect the size and friction of the roller and the small thickness of the platform. Assume = 28° Answer: 8- L H₁ B
The crate pulled by a man as shown weighs 200 N. Supposed that the static friction coefficient between the contact surfaces is 0.25. Determine the following: a.) The value of angle alpha (ᾳ) to obtain the smallest possible value of the pulling force the man exerted so that the crate is on the verge of moving. b.) The smallest value of the pulling force the man exerted, c.) The normal reaction between the contact surfaces (Crate and Horizontal floor).
