26. (III) Two wires run from the top of a pole 2.6 m tall that supports a volleyball net. The two wires are anchored to the ground 2.0 m apart, and each is 2.0 m from the pole (Fig. 9–66). The tension in each wire is 115 N. What is the tension in the net, assumed horizontal and attached at the top of the pole? \2.0 m -2.0 m FIGURE 9-66 Problem 26. 2.6 m 2.0 m-

6) The system shown in in equilibrium. A mass of 225 kg hangs from theend of the strut, which is connected by a hinge to the ground and makes anangle of 45 degrees with the ground. The strut has a mass of 45.0 kg. Asupport cable is attached from a wall to the center of the strut and it makesan angle of 70 degrees with the vertical wall. a) Find the tension in the cable holding up the strut, which make anangle of 70 degrees with the wall. b)  Find the horizontal and vertical forces exerted on the strut by the hinge.

A horizontal 4.0 m long 5.0 N uniform bar at one end is attached to a wall by a frictionless hinge; and at the middle of the bar there is a vertical cable pulling down 7.0 N, and at the middle of the bar there is also a cable that is at 45 ° to the horizontal pulling up as shown. ii) What is the magnitude of the horizontal component of the force on the bar due to the hinge?

a meter log is a uniform bar of mass m = 77 kg. You want to support it at a rest parallel to the ground. so you place it on a triangle support at 33 cm mark and tie it with a rope on the ground at the 28 cm mark. A) draw your own configuration out. calculate the tension of the rope ____ N, downward, upward, right, left, or none  and support force provided by the triangle support _______ N, downward, upward, right, left, or none    b) suppose a gumdrop (point mass mb = 14.00 kg) hangs on to the meter log at the 91 cm mark How large will the tension be on the rope? ______ N conceptually explain why it should increase, decrease, or stay the same, compared to part A.    C) Now with everything including the gumdrop, the triangle support has been moved away from the rope, to the end of the meter log.Explain why the system itself cannot stay balanced anymore, and the rope goes (T→0).  Calculate: rotational inertia of the system below. I = _______ kg·m2Calculate the sizes (+ only) of both the…

As the angle between two concurrent angles decreases, does the magnitude of the force required to produce equilibrium increase, decrease, or the stay the same?
