Your car is stuck in the mud. you have 2 pulleys, rope, and a sturdy tree. ignoring friction how much force can you apply to the car if you are able to pull on the rope with 150lbs of force?

Cut line, 2/3 and 1/3

Secure end of shorter line to tree.

Reeve through block at car and secure to the hook on your second block which will be a traveling block

Now secure the end of your longer line to the tree

Run that line through the sheeve on the traveling block

now look at forces
tension T in line you pull so 2T on traveling block
2T on line from traveling block to car and thus also from car to tree

so total of 4 T on car

4 * 150 = 600 pounds. That should do it.

To determine the force that can be applied to the car using the pulleys and rope, we need to understand the concept of mechanical advantage.

In this scenario, we have two pulleys and a rope. Each pulley system provides a mechanical advantage of 2. This means that for every 1 lb of force applied to the rope, the car will experience a force of 2 lbs.

Since the force applied to the rope is 150 lbs, we can calculate the force applied to the car:

Force applied to car = Mechanical advantage * Force applied to rope

In this case, the mechanical advantage is 2 and the force applied to the rope is 150 lbs.

Force applied to car = 2 * 150 lbs = 300 lbs

Therefore, if you are able to pull on the rope with 150 lbs of force, the car will experience a force of 300 lbs (ignoring friction).
