The figure below shows a bird feeder that weighs 158.9 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 N Right cable N bottom cable N

A uniform plank of length 2.00 m and mass 26.0 kg is supported by three ropes, as indicated by the blue vectors in the figure below. Find the tension in each rope when a 710–N person is d = 0.500 m from the left end. Answer the 3 boxes below:

A mass M1 = 4.1 kg mass is suspended from the ceiling and a mass M2 = 4.3 kg is suspended under it, as shown. The tensions in the strings are labeled  and . A hand exerts an upward force of 22 N on the lower mass mass. Calculate the magnitude of the tension T1

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.
