Screw Jack Velocity Ratio Calculation
What is the formula to calculate the velocity ratio of a screw jack?
Given data:
Length; $L=6$ cm
Pitch; $p=0.3$ cm
Answer:
The velocity ratio of a screw jack can be calculated using the formula:
$$VR = \frac{2\pi L}{p}$$
To calculate the velocity ratio of a screw jack, we use the formula:
$$VR = \frac{2\pi L}{p}$$
Where $L$ is the length of the screw jack and $p$ is the pitch of the screw jack.
Substitute the given values:
$$\begin{gathered} VR = \frac{2\pi \times (6 \text{ cm})}{(0.3 \text{ cm})} \\ = 40\pi \\ \approx 125.71 \end{gathered}$$
Therefore, the velocity ratio of a screw jack is approximately 125.71.
