A plane is inclined at an angle \(\theta\) to the horizontal. Its velocity ratio is
- A. \(sin\theta\)
- B. \(tan\theta\)
- C. \(\frac{1}{sin\theta}\)
- D. \(\frac{1}{tan\theta}\)
Correct Answer: C. \(\frac{1}{sin\theta}\)
Explanation
Velocity ratio = \(\frac{Effort distance}{Load distance}\)
On an inclined plane, it is the inverse of \(sin\theta\) = \(\frac{1}{sin\theta}\)
