Determine the force T that will produce impending motion upward of the 500-lb weight in Figure P7–38. (Assume a coefficient of friction of 0.23.) Also find the minimum force T required to hold the 500-lb weight.

draw free body diagram and A and B please. picture is pretty clear! Block is labeled A (under A is 25 degrees) above is 45 degrees and F pulling down is 50 degrees

The crate shown has a mass of m 20 kg and is being pulled up a plane at 0 25 degrees (to the horizontal) by a cord parallel to the plane, as shown in the following figure:     You are given that the coefficient of friction is u = 0.3.   State the following:   The component of weight parallel to the surface: N.   The component of weight perpendicular to the surface: N.   The normal reaction: N.   The frictional force: N. Calculate the magnitude of the tension, P, in the chord necessary to give an acceleration parallel to the plane of 4 m/s². P is equal to N.
