The drawing shows an A-shaped ladder. Both sides of the ladder are equal in length. This ladder is standing on a frictionless horizontal surface, and only the crossbar (which has a negligible mass) of the " A " keeps the ladder from collapsing. The ladder is uniform and has a mass of 15.2Kg. Det k mine the tension in the crossbar of the ladder.
A 2.4 m ladder rests on a vertical wall as shown in the figure. The ladder has 7 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 friction. If a worker weighs 360 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.
A homeowner is trying to move a stubborn rock from his yard. By using a a metal rod as a lever arm and a fulcrum (or pivot point) the homeowner will have a better chance of moving the rock. The homeowner places the fulcrum a distance d = 0.244 m from the rock, which has a mass of 365 kg, and fits one end of the rod under the rock's center of weight. If the homeowner can apply a maximum force of 695 N at the other end of the rod, what is the minimum total length L of the rod required to move the rock? Assume that the rod is massless and nearly horizontal so that the weight of the rock and homeowner's force are both essentially vertical. The acceleration due to gravity is g = 9.81 m/s?. %3D L =
After an unfortunate accident occurred at a local warehouse, you were contracted to determine the cause. A jib crane collapsed and injured a worker. An image of this type of crane is shown in the figure.The horizontal steel beam had a mass of h 81.70 kg per meter of length, and the tension in the cable was T = 11520 N. The crane was rated for a maximum load of 500 kg. If d = 6.160 m, s = 0.486 m, x = 1.450 m, and h = 2.160 m, what was the magnitude of Wt (the load on the crane) before the collapse? The acceleration due to gravity xr is g = 9.810 m/s². W WL = N What was the magnitude of force Fp at the attachment point P? Fp =
