5. An adjustable tow bar connecting the tractor unit H with the landing gear J of a lar aircraft is shown at Fig. 5. Adjusting the height of the hook F at the end of the tow i is accomplished by the hydraulic cylinder CD activated by a small hand pump (1 shown). For the nominal position shown of the triangular linkage ABC, calculate force P supplied by the cylinder to the pin C to position the tow bar. The rig has a to mass of 50 kg with centre of mass at G and is supported by the tractor hitch at E. Assu there is no bending of the pin at E and ACB is not connected to the horizontal link [ Ans : 298 N ].

Problem 4c: Find the force P, required to maintain equilibrium in the position shown. Also find the support reactions in the bearings at A and B. The bearing at B supports thrust, while the bearing at A does not. 500 lb 150 lb 12 in. 12 in. 200 lb 18 in. 14 in. 14 in.

A rear suspension system for a front wheel-drive vehicle is shown here. Spring EF is offset behind member CD. The normal force due to contact between 2 wheel and the road is 4200 N. Assume the weight of the wheel and suspension system components is negligible. (a) Determine the magnitude of the force in member CD. Is the member in tension or compression? (b) Determine the support reactions at A. (c) Determine the unstretched length of the spring EF given a spring constant of 150 kN/m. 60 mm 1130 mm 60 mm 245 mm D 220 mm F 260 mm E B 165 mm 90 mm F = 4200 N

Please solve for all and include all steps. Thx

One of the smooth vertical walls supporting end B of the 230-kg uniform shaft is turned through a 21° angle as shown here. End A is supported by the ball-and-socket connection in the horizontal x-y plane. Calculate the magnitudes of the forces P and R exerted on the ball end B of the shaft by the vertical walls C and D, respectively. Assume a = 5.6 m, b = 2.3 m, L = 6.5 m, and 0 = 21° Answers: P = 2245 R = H. B a L D N A !N b
