5. In order to raise the lamp post from the position shown, a force F= 200 lb. is applied on the cable. Determine the components of the force F perpendicular and parallel to the post. B A 20 ft 75° -10 ft- 6. Determine the horizontal and vertical components of the force F in problem 5 above.

The jaws and bolts of the wood clamp in Fig- are parallel. The bolts pass through swivel mounts so that no moments act on them. The clamp exerts forces of 300 N on each side of the board. Treat the forces on the boards as uniformly distributed over the contact areas and determine the forces in each of the bolts. Show on a sketch all forces acting on the upper jaw of the clamp. D 100 mm 150 mm B H00 mm75 mm-100 mm-

1: When a force of 2 lb is applied to the handles of the brad squeezer, it pulls in the smooth rod AB. Determine the force P exerted on each of the smooth brads at C and D. (Note that P is not an external force applied to this system, it is shown in the figure to show you where force P is acting within the system (between the thin rods and the wood block.) 2 lb 0.25 in. -2 in- P E 1.5 in. 1 in.f 1.5 in. B D - 2 in.- 2 lb

The system shown consists of three cables; 1, 2 and 3. Cable 1 passes through a frictionless pulley. A 6 kg mass is suspended. Determine the force in cable 3 considering the following data: y1 = 1.3 m, y2 = 1.1 m, y3 = 1.8 m, and x1 = 2.7 m.

4. Not a graded question.

(Please, show all process. ) Use the method of MEMBERS to determine the true magnitude and direction of the forces in members1 and 2 of the frame shown below in Fig 3.4.

30 cm 18 cm Hom Scm Hom Sum 2. The 30 cm handle is connected rigidly to the 5cm bar at a right angle. Determine the force developed at A if a force P = 100 N is applied perpendicular to the handle when the handle is at the position indicated.

The force P on the handle of the positioning lever produces a vertical compression of 56lb in the coiled spring in the position shown. Determine the magnitude of the corresponding force exerted by the pin at O on the lever. Assume a = 3.4in. b = 8.6in.

Chapter 3, Problem 3/073 The 46-lb rectangular access door is held in the 90° open position by the single prop CD.
