Please help. Written on paper not typed on computer or keyboard please. Need help on both questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.

Problem 2 (6 points): Blocks A, B and C have weights 50 lb, 25 lb and 15 lb. Block A is tied to wall by a cable. Force P is applied to a cable tied to block B. Coefficient of static friction between blocks A and B is 0.3, between blocks B and C 0.359, between C and ground D is 0.32. a) State the cases of impending motion as the horizontal force P is applied to block B. b) Assuming one of the stated cases of impending motion, draw proper Free Body Diagrams for the assumed case of impending motion. Label the assumed case of impending motion. c) Determine the smallest force P needed to cause impending motion. Justify your answer. d) Determine tension in cable A, from your final answer for the force P. A B D

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).

A box of mass 10 kg rests in limiting equilibrium on a rough plane inclined at 20° above the horizontal. Find the coefficient of friction between the box and the plane.

The uniform bar and the homogeneous cylinder each have a mass of 24 kg. The static coefficient of friction is μs at A, B, and C (the three points of contact). (a) Assuming equilibrium, calculate the normal and friction forces at A,B and C. (b) What is the smallest value of μs necessary for wquilibrium?
