Calculate the effort force required for a screw jack with our Screw Jack Force Calculator. Get accurate results instantly with our easy-to-use tool!
A Screw Jack Force Calculator helps users quickly determine the force needed to lift a load using a screw jack. This tool simplifies complex calculations, making it easier for engineers, mechanics, and DIY enthusiasts to understand the effort required for lifting different weights.
A screw jack is a mechanical lifting device that uses a screw mechanism to raise or lower heavy loads. It works based on the principle of a simple machine, converting rotational motion into linear motion. Screw jacks are commonly used in car jacks, industrial applications, and machinery maintenance.
The force required to lift a load using a screw jack depends on the load weight, screw pitch, and efficiency. The standard formula to determine the effort force (P) is:
P = (W × tan(α + φ)) / (π × d × η)

Our Screw Jack Force Calculator is designed for easy and quick calculations. Follow these simple steps:
Let’s assume a load of 5000 N, a screw mean diameter of 0.02 m, a lead angle of 5°, a friction angle of 10°, and an efficiency of 0.8.
Using the formula:
P = (5000 × tan(5° + 10°)) / (π × 0.02 × 0.8)
After solving, the required effort force (P) will be displayed in Newtons (N).
| Load Weight (N) | Mean Diameter (m) | Lead Angle (°) | Friction Angle (°) | Efficiency | Effort Force (N) |
|---|---|---|---|---|---|
| 5000 | 0.02 | 5 | 10 | 0.8 | 158.1 |
| 10000 | 0.03 | 6 | 12 | 0.75 | 282.4 |
| 20000 | 0.04 | 7 | 14 | 0.7 | 552.7 |
The Screw Jack Force Calculator is an essential tool for anyone working with lifting mechanisms. Whether in automotive, industrial, or engineering applications, knowing the exact effort force helps in selecting the right screw jack for the job. Use this tool to save time and ensure accuracy in your calculations.
A screw jack’s efficiency depends on factors like thread type, material, and lubrication. Typically, efficiency ranges from 30% to 80%.
A smaller pitch requires less force but more turns, while a larger pitch requires more force but fewer turns.
Friction affects the amount of force needed to lift the load. Higher friction increases the effort force required.
No, hydraulic jacks work differently and require pressure-based calculations. This calculator is specifically for screw jacks.
Yes, square threads and acme threads have different efficiencies, which impact the required effort force.
