Problem 70PP

A Simple Solution for a Stuck Car If your car is stuck in the mud and you don’t have a winch to pull it out, you can use a piece of rope and a tree to do the trick. First, you tie one end of the rope to your car and the other to a tree, then pull as hard as you can on the middle of the rope, as shown in Figure P4.68a. This technique applies a force to the car much larger than the force that you can apply directly. To see why the car experiences such a large force, look at the forces acting on the center point of the rope, as shown in Figure P4.68b. The sum of the forces is zero, thus the tension is much greater than the force you apply. It is this tension force that acts on the car and, with luck, pulls it free. When you are pulling on the rope as shown, what is the approximate direction of the tension force on the tree? A. North B. South C. East D. West

Step-by-Step Solution:

Step 1 of 1 The force of the car is greater than the applied force so the tension force is more, where the applied force will large but which acts opposite to that applied force. Tension is a pulling force which exerts when the mass is attached to rope, cable, or...
