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.
