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. 0.90 m 0.40 m 0 25⁰ 61%

The distance between two telephone poles is d = 54.0 m. When a 1.20 kg bird lands on the telephone wire midway between the poles, the wire sags h = 0.206 m.   How much tension (in N) does the bird produce in the wire? Ignore the weight of the wire

A 0.237 kg book rests at an angle against one side of a bookshelf. The magnitude and direction of the total force exerted on the book by the left side of the bookshelf are given by   |FL| = 1.01N           θL=63.0°   What must the magnitude |FB| and direction θB of the total force exerted on the book by the bottom of the bookshelf be in order for the book to remain in this position?

A window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 192 N and is 2.9 m long. What is the tension in each rope when the 710-N worker stands 1.16 m from one end? smaller tension N larger tension N

A 2.0-m-long rod has a density in kilograms per meter A = a + bx ,where a = 1.0 kg/m, b = 1.0 k9/m², and x is the distance from the left end of the rod. The rod rests horizontally with each end supported by a scale. The force exerted by the left scales is 39.2 N 22.9 N 16.3 N 4.0 N 32.6 N

An 88 kg person stands on a uniform ladder 4.0 m long, that weighs 100 N, as shown in the figure(Figure 1). The floor is rough; hence, it exerts both a normal force, f1, and a frictional force, f2, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, f3. Figure f₁ mg f3 a-3.8 m 1 of 1 Part A Using the dimensions given in the figure, find the forces exerted on the ladder when the person is halfway up the ladder.

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?. (c) What is the magnitude of the force exerted on the large box by the small box in this case? (d) What is the magnitude of the force exerted on the large box by the surface in this case? N

A 100 kg man stands 1 m from the end of a 4 m scaffold suspended by two ropes. Theweight of the scaffold is 750 N. What are the tensions T1 and T2 in the supporting ropes such thatthe system is balanced in equilibrium?

A 5 kg beam 2 meters long is used to support a 10 kg sign by means of a cable attached to a building. The signs hangs from the end of the 2 m long beam, and the cable makes a 40 degree angle with the beam. What is the tension in the cable?
