PHYSICS 2010 LAB: Introduction to Torques and Rotational Equilibrium PartI . Touger.-revised 1716 Overview In this lab you will do some explorations to develop the ideas of toryue and retational eqilsbrium. You will then apply the ideas to further situations in Part I the following week a. Have two people push hard (but equally hard) on both sides of the lab table, as in (a) above, so that EF-0. Does the table move? The tabie doeen't move b. What happens if, pushing as hard as before, the two people offset their pushes more and more, as in (b) and (c) above? Is it still true that F-0? Does the table , remain stationary? yes, it remoineed statono c What is the effect of offsetting the equal and opposite forces further and further to opposite sides? How does the effect that the forces have on the table depend on how far to either side of the center line they are exerted? d. Does the effect also depend on how big the two equal and opposite forces are Although equal and opposite forces produce equilibrium for motion along a straight line (sometimes called translational equilibrium), they do not produce rotational equilibrium unless they are exerted along the same straight line. IfExplanation / Answer
(c) It becomes easier to rotate the table as the torque stop balancing each other.
(d) Yes. The torque applied is dependent on the force applied.
