A 22 kg loudspeaker is suspended 2.4 m below the ceiling by two 2.70 m long cables that angle outward at equal angles. What is the tension in each of the cables?

1. The figure shows a horizontal steel beam with mass M = 500 kg and length L = 2.0 m held against a vertical wall by a taut cable with 0 = 60°. A ball with mass m = 200 kg is attached via a short cable at a distance x 1.5 m from the wall. = a. Draw an extended force diagram for the steel beam, drawing the direction of the forces and the location of the forces acting on the beam. Ꮎ X m b. Using the contact point between the wall and the beam as your pivot point for torque calculations, balance the torques created by all the forces acting on the beam to determine the magnitude of the tension force that the cable exerts on the beam. C. Balance the forces in the x- and y-directions to determine the x- and y-components of the force that the wall exerts on the beam.

Find the magnitude of the tension in each supporting cable shown below. In each case, the weight of the suspended body is 50 N and the masses of the cables are negligible. T₁ 45° T3 (a) T₂ T₁ 60° T3 (b) 45° T2

Two identical, side-by-side springs with spring constant 240 N/m support a 2.00 kg hanging box. Each spring supports the same weight. By how much is each spring stretched?

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.
