Chapter 3, Problem 30P

The homogeneous 200-lb sign is suspended from three wires. Find the tension ineach wire.

A 12.0 kg weight hangs from a 7.50 m pole as illustrated in the diagram.  The pole has a mass of 8.0 kg.  Determine the tension in the cable, and the "Frictional" and "Normal" forces felt from the wall.

0.4 m 1.5 m 10.4 m 0.8 m 1.5 m Three vertical wires are used to support a rectangular plate which weighs 500 N. Determine the tension in the wires. IN

Find the maximum weight of the flowerpot that can be supported without exceeding a cable tension of 50 lb in either cable AB or AC. 4 S 30" A

Determine the tension in the cable at B, given that the uniform cylinder weighs 350 lb. Neglect friction and the weight of bar AB.

The man in the picture below has a weight (not a mass) of 600Newtons. Find the tension in all three ropes. Hint: draw two free body diagrams, one for the man, one for the "knot" where the three ropes join together. 37.0° 600 N

The pin at C is in a smooth slot. s in: Determine the magnitude of of the x-component of the reaction force at A, Ax= N. Determine the magnitude of of the y-component of the reaction force at A, Ay= N. Determine the magnitude of of the external moment applied at A, MA= Nm. O O :

2m 1m 1m -2m- 2m 2m The crate weighs 450 kg andis supported by three cables as shown in the figure 3 m below. D a. Draw a free-body diagram for point A b. Express the tension in each cable in terms of the unit vector andits unknown magnitude c. Determine the magnitude of the tension in each cable d. Whatis the maximum weight for a cratel that can be supported if the maximum tension in any çable is 900 kg?
