In order to apply the most torque to a screw, you should: use a wrench with a long handle use a wrench with a short handle there would be no difference
Two people sit on a seesaw. They sit in positions such that the seesaw is balanced in a horizontal position. True/False: The two people must weigh the same amount. true false
If an object is in equilibrium: the net force on it must be zero the net torque on it must be zero both of the above neither of the above
Ralph noticed that both torque and work are obtained by multiplying a force times a distance. He wants to know: how are they different? Do they have the same units? What can you tell Ralph to help him out? Work is done on an object over a period of time--and over a certain distance having a parallel component--whereas torque is basically a force applied to the object at an instant of time, with the force applied away from the pivot at a given distance (having a perpendicular component). They do have the same units, but represent very different things. Therefore the units of torque are usually written as Nm, whereas the units of energy & work are usually written as J.
