Question 13

Simple Machines

Which of the following graphs correctly represents the relationship between the load and the velocity ratio of a machine?

Diagram for this question
  1. A.Graph A
  2. B.Graph B
  3. C.Graph C
  4. D.Graph D
Show the answer and explanation

Answer: B (Graph B)

Explanation

Velocity ratio depends only on the design of the machine (distance moved by effort ÷ distance moved by load), so it stays the same whatever the load: a horizontal line, graph B.
