Question

13) A four pulley system is required to lift a load force of 20000 Newton's. What is the effort force required to lift this load? a) 5000 N b) 800000 N c) 5000 kg d) 10000 N

Answer 1

The required effort force to lift a load of 20000 Newton with a four pulley system is

, (a) is the correct answer.

Answer 2

## Step1: To calculate the required effort force, we need to apply the principle of mechanical advantage.## Step2: A simple pulley system allows us to evenly distribute the load force across multiple pulleys. ## Step3: Thus, the load or output force can be divided by the number of pulleys to determine the input force, following the equation **Input force = Output force / Number of pulleys**.## Step4: Here, the given output force is 20000 Newton and the number of pulleys is 4.## Step5: Substituting the given values in the equation from step 3, we get **Input force = 20000 N / 4 = 5000 N.**
