Wheel Force Calculator

Wheel force refers to the rotational force applied to a wheel, which creates torque. It’s calculated using the formula: Torque (τ) = Force (F) × Radius (r). The force is typically applied tangentially to the wheel’s edge, and the radius is the distance from the center of the wheel to the point where the force is applied.

For a given torque, a larger wheel radius requires less force to achieve the same rotational effect, while a smaller radius requires more force. This is because torque is the product of force and radius (τ = F × r), so to maintain the same torque with a larger radius, the force can be reduced proportionally.

Torque is a rotational force that causes angular acceleration, measured in Newton-meters (Nm). Power is the rate at which work is done, measured in Watts (W). For wheels, power is the product of torque and angular velocity (P = τ × ω). While torque determines the wheel’s ability to overcome resistance, power determines how quickly work can be done.

If you know the mass (m) and linear acceleration (a) of a vehicle, you can calculate the force needed using Newton’s second law: F = m × a. Then, to find the torque required at the wheel, multiply this force by the wheel radius: τ = F × r. This gives you the torque needed to achieve the desired acceleration.
