2. A 2.4 m ladder rests on a vertical wall as shown in the figure. The ladder has seven rungs and the rungs are spaced 0.30 m apart, and the top and bottom rungs are 0.30 m from their respective ends of the ladder. Surfaces at A and B both have the same coefficient of В friction. If a worker weighs 630 N and stands on the middle rung, determine the minimum value of the coefficient of friction so that the ladder does not slide. Neglect the weight of the ladder. 0 = 60° A

35.0° Dinysics Demos SuDDly Co. The pole is held horizontally by a massless wire under 305 N of tension, connected at a 35° angle. A 8 kg sign hangs from the end of the 4 meter pole. The pole has mass 4 kg. How far away is the wire is attached from the wall? Answer in meters to 3 sig figs.
Consider a rigid steel beam of length L = 14 m and mass mb = 405 kg resting on two supports, one at each end. A worker of mass mw = 68 kg sits on the beam at a distance x from support A. Refer to the figure, though note that it is not drawn to scale. a. When the worker sits at a distance x = 7.5 m from support A, calculate the force, in newtons, that support B must exert on the beam in order for it to remain at rest. Use g with three significant figures. b. The force exerted on the beam by support A is measured and found to be FA = 2240 N. At what distance x, in meters, from support A is the worker sitting now?
