3.2 Worked Examples 3.2.1 Examples of Rigid Objects in Static Equilibrium 1. The system in Fig. 3.1 is in equilibrium with the string in the center exactly horizontal. Find (a) tension T1, (b) tension T2, (c) tension T3 and (d) angle θ. [HRW5 13-23]
8.3 A 2-kg ball is held in position by a horizontal string and a string that makes an angle of 30° with the vertical, as shown in the figure. Find the tension T in the horizontal string.
In the system below the pulley and ramp are frictionless and the block is in static equilibrium. What is the mass of the block on the ramp? A man pulls a 50 kg box at constant speed across the floor. He applies a 200 N force at an angle of 30°. Sum the forces in the x-direction. What is the value of the frictional force opposing the motion?

a. What is the value of the tension force? b. What is the value of the normal force? 4. In the system to the right, the pulley and ramp are frictionless and the block is in static equilibrium. What is the tension in the connecting cord? What is the mass of the block on the ramp? 5. A man pulls a 50.0 kg box at constant speed across the floor.
An object is in static equilibrium (it is not moving) IF 1) it is not translating (not moving up, down, left, or right) AND 2) it is not rotating (not spinning CW or CCW)
5. What must the tension in each cable be in the diagram in order to support the cargo in static equilibrium? Note that pulleys only 50° 30° change the direction of the force, not the magnitude. 1000 N
