Engineering Calculators: Ohm's Law, Force, Gears & Beams

Engineers solve electrical, mechanical and structural problems daily. This guide covers the free calculators on Taskly's engineering tools page.

Electrical

The Ohm's law calculator solves voltage, current and resistance, and the resistor color code decodes bands.

Mechanical

The force calculator applies F=ma, the gear ratio calculator relates teeth to speed and torque, and the power to weight ratio measures performance.

Structural

The beam deflection calculator estimates deflection for common beams and loads.

Power

The power consumption calculator estimates energy use and cost.

Frequently Asked Questions

How do I use Ohm's law?

Enter any two of voltage, current and resistance to compute the missing value instantly, including power.

How do I calculate force?

Enter mass and acceleration to get force in newtons, or solve for mass or acceleration when the other two are known.

How do I compute gear ratios?

Enter the number of teeth on the driving and driven gears to get the ratio, speed and torque output.

Can I check beam deflection?

Yes. The beam deflection calculator estimates deflection and slope for common beam types and loading conditions.
