- In the figure, a motor weighing 3000 N hangs on a chain attached by an O-ring to two other chains, one attached to the ceiling and the other to the wall. Calculate the tensile force acting on the chain attached to the wall. Consider that the weights of the chains and the ring are negligible.A uniform beam of length L = 11.7 meters and mass of 109.3 kg is pinned at one end and is being supported by a wire as shown. The wire is connected to the beam x = 3.3 meters from the pin. A person of mass 81.6 kg is standing all the way out on the edge of the beam. If θ = 17.3 degrees and φ = 79.4 degrees, what is the tension in the wire?How far from Q 2 must Q 3 be located so that the forces on Q 2 are at equilibrium ? ( Ans: 16.5 cm)

- 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?While installing new spark plugs in your car, the manual specifies they be tightened to 74 Nm. If you can only apply a force to the wrench 21 cm from the plug, and only at an angle of 53 degrees, What magnitude force should you apply to the wrench?
