Problem4A person is moving a 250N box as shown in the figure below. He is pulling the box at an angleB above the horizontal. If you know that the floor has a friction against the motion of thebox, and the pulling force T-65% (0.65) of the normal force N, and the friction coefficient is0.26, determine the value of the angle B.

Pls answer asap. Badly need it. Three identical blocks are placed on top of each other on a horizontal plane. Each block has a weight of 110 lb and the coefficient of friction between all surfaces is 0.25. If the upper most block is prevented from moving by a horizontal cable to a vertical wall, find the horizontal force that must be applied at the middle block without causing motion to impend.
