Step by Step Written Solution
Hi, let's solve this physics problem together. We have a system of three pulleys, and we need to find the weight of load P given that each pulley weighs 10 Newtons and the applied force F is 30 Newtons.
Analyzing the Pulley System
Let's analyze the forces starting from the right, where the force F is applied. Since the rope passes over the fixed pulley, the tension in this rope is 30 Newtons.
Now, let's look at the middle pulley. It is a movable pulley supported by two segments of the rope with tension T1. The total upward force on this pulley is 2 times 30 Newtons, which equals 60 Newtons.
This middle pulley must support its own weight of 10 Newtons and the tension of the rope segment going down to the bottom pulley. Let's call that tension T2. So, 60 equals 10 plus T2.
Solving for T2, we subtract 10 from 60, giving us 50 Newtons for the tension supporting the bottom pulley.
