1. What is Stem Torque?

Stem torque refers to the rotational force applied to a stem or shaft, calculated as the product of the applied force and the radius (distance from the axis of rotation). It is a fundamental concept in mechanical engineering and physics.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( Force \) — Applied force in Newtons (N)
• \( Radius \) — Distance from axis of rotation in meters (m)
• \( Torque \) — Resulting torque in Newton-meters (Nm)

Explanation: The torque increases linearly with both the applied force and the radius at which the force is applied.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for designing mechanical systems, determining appropriate fastener tightness, analyzing rotational systems, and ensuring structural integrity in various engineering applications.

4. Using the Calculator

Tips: Enter force in Newtons and radius in meters. Both values must be positive numbers. The calculator will compute the resulting torque in Newton-meters.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for torque calculations?
A: The standard SI units are Newtons for force, meters for radius, and Newton-meters (Nm) for torque.

Q2: How does radius affect torque?
A: Torque increases proportionally with radius. Applying the same force at a greater distance from the axis creates more rotational force.

Q3: What's the difference between torque and force?
A: Force causes linear acceleration, while torque causes rotational acceleration. Torque is essentially the rotational equivalent of force.

Q4: Can I use different units with this calculator?
A: This calculator uses SI units. For other unit systems, you'll need to convert your values to Newtons and meters first.

Q5: What are typical torque values in mechanical applications?
A: Torque values vary widely depending on the application, from small fractions of Nm in precision instruments to thousands of Nm in heavy machinery.
