are bies tached the plate on the Sons indicated on ant to replace the two forces by a force F exerted through a single cable. 4N 4N

The cable AOB weighs 5.2 N/m. When the horizontal 30-N force is applied to the roller support at B, the sag in the cable is 5 m. Find the span L of the cable.

Cable ABC of length 5 m supports the force W at B. Determine (a) the angles 1 and 2; and (b) the force in each cable segment in terms of W.

You are pushing an80.0 N wheelbarrow as shown inFig. You lift upward on thehandle of the wheelbarrow so thatthe only point of contact betweenthe wheelbarrow and the groundis at the front wheel. Assume thedistances are as shown in the figure,where 0.50 m is the horizontaldistance from the center of thewheel to the center of gravity of thewheelbarrow. The center of gravityof the dirt in the wheelbarrow isassumed to also be a horizontal distanceof 0.50 m from the center of thewheel. Estimate the maximum totalupward force that you can apply to the wheelbarrow handles. (a) If youapply this estimated force, what is the maximum weight of dirt that youcan carry in the wheelbarrow? Express your answer in pounds. (b) If thedirt has the weight you calculated in part (a), what upward force does theground apply to the wheel of the wheelbarrow?

2. The force P = 2 kips is applied to point A, and is supported by cable AB, cable AC, and bar OA. The force P and both cables pull on point A, and bar OA pushes on point A. Determine the forces in cables AB and AC, and in bar OA. You can use Excel to solve the equations, but you don't have to for this one. (Point A lies in the zy plane, and points B and C lie in the xz plane.) 6 ft x 4 ft B 4 ft 12 ft AC D 5 ft P 12 ft

The wheels, axle, and handles of a wheelbarrow weigh W = 55 N. The load chamber and its contents weigh WL = 623 N. The drawing shows these two forces in two different wheelbarrow designs. To support the wheelbarrow in equilibrium, the man’s hands apply a force to the handles that is directed vertically upward. Consider a rotational axis at the point where the tire contacts the ground, directed perpendicular to the plane of the paper. Find the magnitude of the man’s force for both designs.

The system shown consists of 3 cables. For instance; cable C12 joins points 1 and 2. The coordinates of point 1 are (4.5, 0, 0) m, those of point 2 are (0, 7.4, -5.8) m, and those of point 3 are (0, 7.4 , 5.8) m. The force P = 58 kN. Determine the force in cable C12.

It is desired to remove the spike from the timber by appying force along its horizontal axis. An obstruction "A" prevents direct acess, so that two forces, one 400LB and the other "P" are applied by cables as shown. Here we want to investigate the effects of the distance between the spike adn the obstruction on the two forces so replace 8" by "d" in the figure. Determine the magnitude of "P" necessary to insure a resultant "T" directed along the spike. Please show all work and FBD thank you!

Given a system made of the force F, couple M and distributed loads defined by w1 and w2, find the equivalent system at B.Take F = 8 kN, M = 5 kN.m, w1 = 8 kN/m, and w2 = 4 kN/m.Also, d = 1 m.

For the system of forces shown, find the equivalent force-couple system at A. If a single equivalent force were to act at D, determine the length from B to D. Note that based on the figure, since there is no given angle for the 150 N force, the manner of 120 N 100 N 60 N B 1m 270 N-m 150 N 120 N D 1 m 0.5 m 0.5 m 2 m which the distance is indicated in the figure suggests that the 150 N force is perpendicular to the 30° arm of the bar system.
