Answer:
Yes, torque can still be used to solve for the mass of the magnifying glass, even if the bamboo skewers on your mobile are balanced but not quite horizontal.
Torque, also known as the moment of force, is a rotational force that causes objects to rotate. It is calculated as the product of the force and the lever arm distance (perpendicular distance from the force vector to the axis of rotation). In the case of a balanced system, the sum of torques acting on one side of the rotation point is equal to the sum of torques acting on the other side.
When the bamboo skewers on your mobile are not quite horizontal, they create an angular displacement from the horizontal axis. This angular displacement introduces a component of torque that needs to be taken into account when calculating the overall torque acting on the system.
To solve for the mass of the magnifying glass using torque, you would need to consider the forces and lever arms acting on the system. The magnitude of the torque created by the weight of the magnifying glass can be calculated by multiplying the perpendicular distance from the axis of rotation to the point where the weight force is applied.
By setting up equations of torques and considering the balance of the system, you can solve for the unknowns, such as the mass of the magnifying glass. Even if the bamboo skewers are not perfectly horizontal, torque can still be used as long as the system is in equilibrium.
It is important to note that in real-life situations, other factors such as friction, air resistance, and the flexibility of the bamboo skewers may introduce some errors in the calculations. Therefore, a careful analysis and understanding of the system is necessary to obtain accurate results.
