Question

**Physics Experiment: Balancing Masses on a Fulcrum**

In a physics experiment, a metal bar is balanced on a fulcrum. A 5.0 kg mass is placed on the bar, 45.0 cm from the fulcrum, and on the same side, a 2.0 kg mass is placed an unmeasured distance away from the fulcrum. Another mass (12 kg) is placed on the other side of the fulcrum, 50.0 cm away.

**Question:**
How far away is the 2.0 kg mass from the fulcrum?

**Diagram Description:**

The diagram illustrates a lever balanced on a fulcrum. On the left side of the fulcrum, there are two masses:
- A 5.0 kg mass, located 45.0 cm from the fulcrum.
- A 2.0 kg mass, positioned at an unknown distance from the fulcrum.

On the right side of the fulcrum, there is a 12 kg mass placed 50.0 cm away from the fulcrum.

This setup demonstrates the principle of moments, which is used to calculate the unknown distance for balanced forces.

The fishing pole in Figure P10.28 makes an angle of 20.0 with the horizontal. What is the torque exerted by the fish about an axis perpendicular to the page and passing through the anglers hand if the fish pulls on the fishing line with a force F = 100 N at an angle 37.0 below the horizontal? The force is applied at a point 2.00 in from the anglers hands.
Two forces are acting on an object. Which of the following statements is correct? (a) The object is in equilibrium if the forces are equal in magnitude and opposite in direction. (b) The object is in equilibrium if the net torque on the object is zero. (c) The object is in equilibrium if the forces act at the same point on the object. (d) The object is in equilibrium if the net force and the net torque on the object are both zero. (e) The object cannot be in equilibrium because more than one force acts on it.
Casting of molten metal is important in many industrial processes. Centrifugal casting is used for manufacturing pipes, bearings, and many other structures. A cylindrical enclosure is rotated rapidly and steadily about a horizontal axis, as in Figure P7.62. Molten metal is poured into the rotating cylinder and then cooled, forming the finished product. Turning the cylinder at a high rotation rate forces the solidifying metal strongly to the outside. Any bubbles are displaced toward the axis so that unwanted voids will not be present in the casting. Suppose a copper sleeve of inner radius 2.10 cm and outer radius 2.20 cm is to be cast. To eliminate bubbles and give high structural integrity, the centripetal acceleration of each bit of metal should be 100g. What rate of rotation is required? State the answer in revolutions per minute. Figure P7.62
