A man drags a 67-kg crate across the floor at a constant velocity by pulling on a strap attached to the bottom of the crate. The crate is
tilted 25° above the horizontal, and the strap is inclined 61° above the horizontal. The center of gravity of the crate coincides with its
geomentrical center, as indicated in the figure. Find the magnitude of the tension in the strap.

A small box with a weight of 35.0 N is placed on top of a larger box that has a weight of 80.0 N. The system of two boxes is at rest on a horizontal surface (the larger box is in contact with the surface). You apply an additional downward force of 30.0 N to the top of the small box by resting your hand on it. For this problem, use g = 10 N/kg. (a) What is the magnitude of the force exerted on the large box by the small box? (b) What is the magnitude of the force exerted on the large box by the surface? Now, imagine that the horizontal surface is the floor of an elevator, and the boxes are in the elevator, which has an acceleration directed downward of 1.00 m/s?.

A box is at rest on a floor. The box has a mass of 35.0 kg. A force P = 213.0 N is acting to the left at an angle = 31.5° above the horizontal as shown in the figure provided on the right. Between the box and the floor, the coefficient of static friction is Hs = 0.830 and the coefficient of kinetic friction is HK = 0.778. What is the magnitude of the normal force acting on the box?

It is known that the 10 kg pipe will roll up the ramp and not slide on the ramp when P becomes sufficiently large. Using the rolling assumption, find the minimum P required to cause impending motion of the 10 kg pipe up the ramp. Note that the coefficients of friction for the block/ramp, the pipe/ramp and the pipe/block contacts are each 0.30. 18 kg block 35° 10 kg pipe B μg 0.30 for all contacts
The block shown in (Figure 1) has a mass of m = 75 kg, a height H = 1.1 m, and width L = 1.6 m. It is resting on a ramp that makes an angle 0 = 34° with the horizontal. A force P is applied parallel to the surface of the ramp at the top of the block. What is the maximum force that can be applied without causing the block to move? The coefficient of static friction is μs = 0.42, and the center of mass of the block is at the center of the rectangle. What is the maximum magnitude of P that can be applied before tipping would occur, assuming the block does not slip? Express your answer to three significant figures with appropriate units.

The figure below shows a bird feeder that weighs 140.1 N. The feeder is supported by a vertical cable, which is in turn tied to two cables, each of which is attached to a horizontal post. The left cable makes a 60° angle with the post, while the right cable makes a 30° angle. What is the tension in each cable (in N)? left cable right cable bottom cable 60° Bird food 30° N ZZZ N N
The figure below shows a block weighing 22 N in contact with a vertical wall. Two forces are applied to the block, in addition to gravity, a horizontal force F of magnitude 60 N which pushes the block against a vertical wall and a force P of magnitude 62 N which pushes upward on the bottom of the block parallel to the wall. The coefficient of static friction between the wall and the block is 0.55 and the coefficient of kinetic friction between them is 0.38. Is the frictional force acting on the block static or kinetic, what is its magnitude and in what direction does it point? F P
