H8-4: For the following diagram, bar AB is pinned to collar B which is unthreaded and rests on collar C. The mean radius of the thread is , 1.5 in and the pitch is p 0.2 in. Between the threads of collar C and the threads of the vertical shaft, μ,-0.22 and μ,-0.25. The suspended object is 300 lb. What couple must be applied to the collar C to rotate it at a constant rate, and to cause the object...
Problem 2. Collars A and B are pinned to the bar that is welded to sphere C. A servomotor acting about the pin in collar A applies torque ? to bar AC and force F is applied to collar B with the result that collar A moves downward at a constant specified speed v. The system rotates freely about the vertical axis, so the precession rate ?2 is unknown, but the spin rate is held at a constant value by...
Please help me answer this problem using Instantaneous Centers.
Please write legibly and I will rate well. Thank you.
Collar C is free to slide along a smooth shaft that is fixed at a 45° angle. Member AB is fixed securely to the wall by a pin support at A and member CB is pinned at B and C. If collar C has a velocity of v_C-3 m/s directed up and to the right at the position shown below determine,...

The 10 kg uniform slender bar is pinned at A to the collar, which has an upward acceleration a = 4 m/s along the vertical shaft. If the bar has an angular velocity ω = 3 rad/s as it swings past the horizontal position, determine the magnitude of the reaction at A for this instant.Ans: 43.8 N
A block hangs from the end of bar AB that is 7.50 meters long and connected to the wall in the zz plane. The bar is supported at end A by a ball joint such that it carries only a compressive force along its axis. The bar is supported in equilibrium at end B by cables BD and BC that connect to the zz plane at points C and D respectively with coordinates given in the figure. The z components...
Problem (20 pts) Structure ABCD is supported by a collar at D that can rotate and slide along bar EF, which is fixed and is 2 m frictionless. Structure ABCD makes contact with smooth surfaces at A and C where the normal direction n to the surface at A lies in a plane that is parallel to the xy plane. Force P is parallel to the y axis. If P-10 kN, determine the reactions at A, C, and D P...
A 5 kg collar is attached to a spring and it slides along a
smooth bar. The spring has undeformed length of 35 cm and a
constant k= 700 N/m. The collar is released from rest as shown
below. Determine the force exerted by the rod on the collar
when;
a) The collar is at point A
b) The collar is at point B.
Not that both A and B are on the curved portion of the rod.

Bars AB and BE, each of mass 4.4 kg, are welded together and are pin-connected to two links AC and BD. The assembly is released from rest in the position shown and neglecting the masses of the links, determine the maximum shear force and bending moment of the bars AB and BE. (Round the final answers to two decimal places.) А 30° E 0.5 m 60° С 0.5 m -BO 30° OD For bar AB, The maximum shear force is...
