Question

2 what inference can you make from the graph below? relationship between mechanical advantage, input force, and output force (graph omitted) a a large mechanical advantage means that supplying a small input force results in a large output force. b a large mechanical advantage means that supplying a large input force results in a small output force. c input force is always greater than output force. d input force is always equal to output force

Explanation:

To solve this, we analyze the graph: the x - axis is Mechanical Advantage, y - axis is Force (Newtons). The blue line (Input Force) is low, and the red line (Output Force) rises steeply with increasing Mechanical Advantage.

• Option A: As Mechanical Advantage (MA) increases, Input Force is small (low blue line) and Output Force is large (high red line), so a large MA means small input gives large output. This matches the graph.
• Option B: Contradicts the graph (output force is large, not small, with large MA).
• Option C: The graph shows output force is greater than input force (red line above blue line), so this is wrong.
• Option D: The lines are not equal, so this is wrong.

Answer:

A. A large mechanical advantage means that supplying a small input force results in a large output force.
