This week in lab you observed how a force can apply a torque and rotate an object. Using the concepts of applied force and torque, describe how a doorstop works to keep a door open. Where along the length of the door is the doorstop most effective? (That is, closer or farther from the hinges?) Explain your reasoning using the concepts of force and torque.
