Problem 1-1:Determine a pair of horizontal and vertical components of the 340-lb force of Fig. P1-1. 340b

6.62 Neglect the mass of the pulleys and the link. The block has a weight of 230 lb and the cord is attached to the pin at B. The pulleys have radii of r1 = 2 in. and r2 = 1 in. Determine the force P on the cord. Determine the angle θ that the pulley-supporting link AB makes with the vertical.

Determine the magnitude of the clamping forces (in pounds) exerted on the nut along line aa when two 78-lb forces are applied to the handles as shown. Assume that pins A and D slide freely in the slots in the jaws.

Solve it fast within 10-15minutes ,Its easy one.

A puck weighs 8 lb and rests on the center of the frictionless surface of the ramp supported in equilibrium by ropes AC and BC. Determine the normal force the ramp exerts on the puck as well as the tension in each of the two ropes. g Variable Value Values for dimensions on the figure are given in the following table. Note the figure may not be to scale. a b C d e f g9 36.0 in 45.0 in 13.5 in 27.7 in 45.0 in 18.0 in 35.0 in B The normal force acting on the puck is pounds The tension in rope AC is The tension in rope BC is C pounds pounds

A former student of mechanics wishes to weigh himself t has access only to a scale A with capacity limited to 110 lbs and a small 20- lb spring dynamometer B. With the rig shown he discovers that when he exerts a pull on the rope so that Bregisters 18 lb, the scale A reads 84 lb. What is his correct weight? Answer: Weight= lb

P1 6000N 45° P2 4000N Determine the 60-kg cylinder in Fig. 3-6a. the tension in cables BA and BCnecessary to suppPort the 3-1. The crate has a weight of 550 lb. Determine the force in each supporting cabie.

The loading device is useful in handling 55 gallon drums. Determine the force F necessary to hold a drum in the position shown. So neglect the weight of the device compared to the 575 lb weight of the drum, whose center of gravity is at G. There is enough friction to prevent slipping at the point of contact P. a) magnitude of the normal reaction force at point P.b) Magnitude of force F.

P2: The 50-lb rectangular access door is held in the 90° open position by the single prop CD. Determine the force F in the prop and the magnitude of the force normal to the hinge axis AB in each of the small hinges A and B. 12" 40" C 2 B 48
