A shop sign weighing hangs from the end of a uniform beam as shown. Find the horizontal and vertical forces exerted by the hinge on the beam at the wall.

A heavy boy and a light girl are balanced on a massless seesaw. If they both move forward so that they are one-half their original distance from the pivot point, what will happen to the seesaw?

The torque applied to a wrench is . If the force applied to the wrench is , how long is the wrench?

Two equal forces are applied to a door. The first force is applied at the midpoint of the door, the second force is applied at the doorknob. Both forces are applied perpendicular to the door. Which force exerts the greater torque?

A shop sign weighing hangs from the end of a uniform beam as shown. Find the tension in the support wire at .

Two equal forces are applied to a door at the doorknob. The first force is applied to the plane of the door. The second is applied perpendicular to the door. Which force exerts a greater torque?

A pulley has a bucket of weight hanging from the cord over a well. The pulley has a mass of and radius of . There is a frictional torque of at the axle. Assume the cord has negligible mass and does not stretch or slip on the pulley. Calculate the linear acceleration of the bucket.

Two children are trying to balance on a see-saw. One child has a mass of the other has a mass of . If the see-saw is balanced perfectly in the middle and the child is sitting at one end of the see-saw, how far from the center should the child sit so that the system is perfectly balanced?
