A heavy chandelier with mass 180 kg is hung by chains in equilibrium from the ceiling of a concert hall as shown in the figure below, with 8, = 30.0° and 8, = 70.0°. Assuming the chains are massless, what are the tensions F Frz and Fz in the three chains? FT = FR = FT3 N

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

CM4: A 58 kg circus performer hangs from a bar suspended from a ceiling as shown in the figure. If the bar masses 12 kg (and its weight acts at its center) and has a length of 1.4 m, what is the tension T₂ in the rope? The rope is attached 0.85 m along the bar. تل T₂ 50°

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 20.4 kg mass (m) is suspended by the cable assembly as shown in the figure. The cables have no mass of their own. The cable to the left (T) of the mass makes an angle of 0.00° with the horizontal, and the cable to the right (T2) makes an angle (02) of 30.1°. If the mass is at rest, what is the tension in each of the cables, T and T2? The acceleration due to gravity T, T, is g = 9.81 m/s². N T1 = m N T2 =

The figure shows an arrangement in which four disks are suspended by cords. The longer, top cord loops over a frictionless pulley and pulls with a force of magnitude 88.2 N on the wall to which it is attached. The tensions in the shorter cords are T₁ = 69.1 N, T₂ = 40.5 N. and T3 = 6.76 N. What are the masses of (a) disk A, (b) disk B, (c) disk C, and (d) disk D? (a) Number i (b) Number i (c) Number i (d) Number i Units Units Units Units

A 30.6 kg mass (m) is suspended by the cable assembly as shown in the figure. The cables have no mass of their own. The cable to the left (T|) of the mass makes an angle of 0.00° with the horizontal, and the cable to the right (T2) makes an angle (02) of 36.4°. If the mass is at rest, what is the tension in T each of the cables, T¡ and T,? The acceleration due to gravity is g = 9.81 m/s². T = N m T2 = N
