Question

This practical activity allows you to have a theoretical and practical basis regarding physics. static. With the help of the PheT Colorado platform simulator, we will develop a system with known and unknown masses. From this, using the concept of torque, we will calculate the value of each of the masses. Therefore, the objectives of this activity are: 1) Apply the concept of Torque. 2) Determine how to calculate the value of an unknown mass by the principle of equilibrium rotation.

1. Understand that torque (\tau) is the product of force and distance from the pivot point.
2. For a balanced system, the sum of clockwise torques equals the sum of counterclockwise torques.
3. Label the known mass as m_{\text{known}} and the unknown mass as m_{\text{unknown}}.
4. Position each mass at a distance from the pivot: d_{\text{known}} for the known mass and d_{\text{unknown}} for the unknown mass.
5. The equation for equilibrium is:

m_{\text{known}} \cdot g \cdot d_{\text{known}} = m_{\text{unknown}} \cdot g \cdot d_{\text{unknown}}

6. Simplify the equation assuming equal gravitational acceleration on both sides:

m_{\text{unknown}} = \frac{m_{\text{known}} \cdot d_{\text{known}}}{d_{\text{unknown}}}

7. Thus,

m_{\text{unknown}} = \frac{\tau_{\text{known}}}{g \cdot d_{\text{unknown}}}

Answer: m_{\text{unknown}} = \frac{m_{\text{known}} \cdot d_{\text{known}}}{d_{\text{unknown}}}
