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
2. For a balanced system, the sum of clockwise torques equals the sum of counterclockwise torques.
3. Label the known mass asm_{\text{known}} m_{\text{unknown}}
4. Position each mass at a distance from the pivot:d_{\text{known}} d_{\text{unknown}}
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}}}
