Torque Formula:
| From: | To: |
Torque calculation determines the rotational force required to turn a wheel or other rotating object. It's a fundamental concept in mechanical engineering and physics that describes how much force is needed to cause rotation.
The calculator uses the torque formula:
Where:
Explanation: The formula calculates the torque required to turn a wheel by multiplying the applied force by the radius, then dividing by the system's efficiency factor to account for energy losses.
Details: Accurate torque calculation is essential for designing mechanical systems, selecting appropriate motors and drives, ensuring proper operation of rotating equipment, and optimizing energy efficiency in mechanical applications.
Tips: Enter force in newtons (N), radius in meters (m), and efficiency as a dimensionless factor (typically between 0 and 1). All values must be positive numbers.
Q1: What is torque measured in?
A: Torque is typically measured in newton-meters (Nm) in the SI system, or pound-feet (lb-ft) in the imperial system.
Q2: How does efficiency affect torque requirements?
A: Lower efficiency means more torque is required to achieve the same rotational effect, as some energy is lost to friction and other factors.
Q3: What is a typical efficiency value for mechanical systems?
A: Efficiency values typically range from 0.7 to 0.95 (70% to 95%) for most mechanical systems, depending on the type of bearings, lubrication, and mechanical design.
Q4: Can this formula be used for any rotating object?
A: Yes, this basic torque formula applies to any situation where a force is applied at a distance from a pivot point to create rotation.
Q5: How does radius affect torque requirements?
A: Torque increases linearly with radius - doubling the radius doubles the torque required for the same applied force.
