1. What is Torque Transmitted by Pulley?

Torque Transmitted by Pulley is the amount of torque transmitted by the pulley in mechanical systems. It represents the rotational force that the pulley can transfer through its arms and rim.

2. How Does the Calculator Work?

The calculator uses the torque transmission formula:

\[ M_t = P \times R \times \left( \frac{N}{2} \right) \]

Where:

\( M_t \) — Torque Transmitted by Pulley (N·m)
\( P \) — Tangential Force at End of Each Pulley Arm (N)
\( R \) — Radius of Rim of Pulley (m)
\( N \) — Number of Arms in Pulley

Explanation: The formula calculates the total torque transmitted by multiplying the tangential force at each arm end by the radius of the pulley rim and the effective number of arms (N/2).

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for designing mechanical systems, ensuring proper power transmission, and preventing mechanical failures in pulley systems.

4. Using the Calculator

Tips: Enter tangential force in Newtons, radius in meters, and number of arms. All values must be positive numbers with appropriate units.

5. Frequently Asked Questions (FAQ)

Q1: Why is the number of arms divided by 2 in the formula?
A: The division by 2 accounts for the fact that only half of the arms are effectively transmitting torque at any given moment in a typical pulley system.

Q2: What are typical values for pulley torque transmission?
A: Torque values vary widely depending on pulley size and application, ranging from small fractions of N·m in precision instruments to thousands of N·m in industrial machinery.

Q3: How does pulley radius affect torque transmission?
A: Larger radius pulleys transmit more torque for the same tangential force, as torque is directly proportional to the radius.

Q4: Are there limitations to this formula?
A: This formula assumes uniform force distribution and ideal conditions. Actual performance may vary due to friction, material properties, and manufacturing tolerances.

Q5: Can this calculator be used for all types of pulleys?
A: This calculator is designed for standard pulley configurations. Specialized pulley designs may require additional considerations.
