A moveable pulley provides MA whereas the fixed pulley changes the direction of the force.Question 2Answera.Trueb.False

Step 1: Break Down the Problem

The question asks whether a moveable pulley provides mechanical advantage (MA) while a fixed pulley simply changes the direction of force. We need to evaluate the roles of both pulley types.

Step 2: Relevant Concepts

1. Moveable Pulley: A moveable pulley allows you to gain mechanical advantage. This means you can lift heavier loads with less effort due to the distribution of weight.
2. Fixed Pulley: A fixed pulley does not offer mechanical advantage in terms of force; it only facilitates changing the direction of the applied force.

Step 3: Analysis and Detail

• Mechanical Advantage (MA): For a moveable pulley, the mechanical advantage can be calculated as the ratio of the load to the effort, allowing you to lift twice the weight for the same amount of effort applied.
• Fixed Pulley Functionality: When using a fixed pulley, you pull down to lift the load up, which indeed changes the direction of force but does not decrease the amount of effort needed.

Step 4: Verify and Summarize

Upon analyzing the functions of both types of pulleys, it is clear:

• A moveable pulley provides mechanical advantage.
• A fixed pulley only changes the direction of the force and does not reduce the force needed.

Final Answer

Answer: a. True
