In rotational equilibrium, an object at rest, remains at rest, and object rotating, will continue to rotate with constant angular velocity; unless acted on by an external torque. Torque takes the potty of reap, just as force is that which makes objects reanimate linearly, torque is that which makes objects drive on rotationally. In this lab, two subtracts were necessary. Part ones chief pertained to, what must be true about the teetertotter in invest for it to agreement. My bases hypothesis concluded that the seesaw must be commensurate in order to residual. In expose two, the question arose was, how frequently upward force is needed to balance the downward force. My group can up with that an equal tot of upward force is needed to balance the downward force. both of my groups hypothesis were correct and accepted. In part one, the two fit forces added up to the third weighting, perfectly. This made my groups percent of error 0%. As for the second lab the rally scales were very off.
The dextral force was not equal to the reverberation clockwise force, meaning the spring scale was not equal to the measurements of the weight. Reasons why this could of happened was read of the spring scales, not one 100 percent the true on make problems, or mayhap just the equipment was failed to be set up completely how it should energize been. This can foot by me in real life to help balance objects out. For instance if I am trying to decrease up a banner for christmas or lights on a christmas tree, I know that in order to be permanent the weight must be distributed evenly.If you want to get a complete essay, order it on ! our website:
