Which factor does NOT affect the velocity ratio of a simple machine?
52. Which factor does NOT affect the velocity ratio of a simple machine?
- Friction in the machine
- Mechanical advantage
- Efficiency of the machine
- Load and effort distances
Answer
The correct answer is: C) Efficiency of the machine
Explanation
The velocity ratio of a simple machine is determined by its mechanical design and the load and effort distances. Factors like friction can affect the efficiency but not directly the velocity ratio.
