Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle? FIGURE P5.76
A brass wire and a steel wire, both of the same length, are extended by 1.0 mm under the same force. Is the cross-sectional radius of the brass wire more, less, or equal to the cross-sectional radius of the steel wire? Explain. Youngs moduli for brass and steel are 1.0 1010 N/m2 and 2.0 1011 N/m2, respectively.
A 20.0-kg horizontal plank 4.00 in long rests on two supports, one at the left end and a second 1.00 m from the right end. What is the magnitude of the force exerted on the plank by the support near the right end? (a) 32.0 N (b) 45.2 N (c) 112 N (d) 131 N (e) 98.2 N
A One end of a metal rod of weight Fg and length L presses against a corner between a wall and the floor (Fig. P14.64). A rope is attached to the other end of the rod. Find the magnitude of the tension in the rope if the angle between the rod and the rope is 90.
One end of a uniform 4.00-m-long rod of weight Fg is supported by a cable at an angle of = 37 with the rod. The other end rests against the wall, where it is held by friction as shown in Figure P12.23. The coefficient of static friction between the wall and the rod is s= 0.500. Determine tile minimum distance x from point A at which an additional object, also with the same weight Fg can be hung without causing the rod to slip at point A.
A tutor told me that the answer to 1b was 10N but I don't understand why it would be 10N for the tension. If that is correct could someone break it down for me?
A man stands a distance d = 0.275 m from the left end of a platform as shown in the figure. The platform is supported by three cables. Find the tension in each cable (in N). Assume the platform is uniform, with length L = 2.00 m and mass 35.0 kg, and the weight of the man is 690 N. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) (b). What If? The man now begins to walk to the right. If each of the cables can support a maximum tension of 800 N, which cable fails first? At what location does this occur (measured in m from the left end of the platform)?

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. i) What is the tension of the upper cable?

A fisherman has caught a fish on his pole, and to keep the pole steady he has to apply an upward force of F2 = 265 N at an angle of 58° with respect to the pole (see figure). The length of his pole is 3.2 m, and he is holding it a distance 0.65 m from the end, where he is applying a downward force F1. Part (a) With how much force, F1, in newtons, does he have to push straight downward on the end of his pole to keep the pole from moving? You may assume the pole is massless. Part (b) What is the mass of the fish on the end of the pole, in kilograms?
Forces F→1, F→2, and F→3 act on the structure of the figure, shown in an overhead view. We wish to put the structure in equilibrium by applying a fourth force, at a point such as P. The fourth force has vector components F→h and F→v. We are given that a= 1.90 m, b = 3.27 m, c = 1.31 m, F1 = 38.1 N, F2 = 18.9 N, and F3 = 2.05 N. Find (a) magnitude of Fh, (b) magnitude of Fv, and (c) d.
