In a simple machine, what is the velocity ratio (VR) if the effort moves through 15 m while the load moves through 3 m?
Answer and explanation
Correct answer: A. 5
- Step 1: Velocity Ratio is defined as: VR = Distance moved by Effort ÷ Distance moved by Load. Step 2. Substitute: VR = 15 m ÷ 3 m = 5. Answer: 5. Why not the others: 0.2 inverts the distance ratio (3/15); 12 is the subtraction (15 - 3); 45 is the product (15 * 3).
