1. What is the Tension in String Formula?

The Tension in String formula calculates the force exerted by a string connecting two bodies on smooth inclined planes. It considers the masses of both bodies, the gravitational acceleration, and the inclinations of both planes to determine the tension force in the connecting string.

2. How Does the Calculator Work?

The calculator uses the Tension in String formula:

\[ T = \frac{m_a \cdot m_b}{m_a + m_b} \cdot g \cdot (\sin(\alpha_1) + \sin(\alpha_2)) \]

Where:

\( T \) — Tension of String (N)
\( m_a \) — Mass of Body A (kg)
\( m_b \) — Mass of Body B (kg)
\( g \) — Gravitational acceleration (9.80665 m/s²)
\( \alpha_1 \) — Inclination of Plane 1 (radians)
\( \alpha_2 \) — Inclination of Plane 2 (radians)

Explanation: The formula calculates the tension force in a string connecting two masses on different inclined planes, accounting for the gravitational forces and the angles of inclination.

3. Importance of Tension Calculation

Details: Accurate tension calculation is crucial for analyzing mechanical systems, designing safe structures, and understanding the forces in connected body systems on inclined surfaces.

4. Using the Calculator

Tips: Enter masses in kilograms, angles in radians. All values must be valid (masses > 0, angles ≥ 0). For degree inputs, convert to radians first (radians = degrees × π/180).

5. Frequently Asked Questions (FAQ)

Q1: Why use radians instead of degrees?
A: Trigonometric functions in mathematical formulas typically use radians as they provide more natural mathematical relationships in calculus and physics equations.

Q2: What if both planes are horizontal?
A: If both inclinations are 0 radians, the tension becomes zero since sin(0) = 0, meaning no net force component along the string direction.

Q3: Can this formula be used for vertical planes?
A: Yes, for vertical planes (π/2 radians or 90°), sin(π/2) = 1, which gives maximum tension contribution from that plane.

Q4: What are typical tension values?
A: Tension values depend on the masses and angles, but typically range from fractions of a newton to hundreds of newtons depending on the system scale.

Q5: Are there limitations to this formula?
A: This formula assumes smooth, frictionless planes and ideal string conditions. Real-world applications may require additional factors like friction and string elasticity.
