Wedge Mechanical Advantage

Summary

Enter wedge length and thickness to instantly calculate its mechanical advantage and ideal output force.

How it works

1. Enter the wedge length (slant length along the slope).
2. Enter the wedge thickness (the widest end, perpendicular to direction of motion).
3. The calculator divides length by thickness to give the ideal MA.
4. Enter an optional input force to see the theoretical output force.
5. Results update instantly as you type.

Use cases

• Estimate the splitting force of an axe or chisel.
• Design door stoppers and calculate their holding force.
• Teach simple machines and mechanical advantage in physics class.
• Compare different wedge geometries before manufacturing.
• Calculate nail or screw driving force multiplication.
• Evaluate ramp or inclined-plane designs in engineering projects.
