Before beginning, I recommend that you understand Torsion by clicking here, since questions are asked from it.
What is inertia?
The inherent property of all objects by which they resist any change in their state of rest or uniform motion along a straight-line path unless acted upon by an external force.
What is the use of mirror in inertia table?
The mirror in an inertia table is used to measure the angular displacement during oscillations, which allows precise tracking of the motion. It helps in determining the period of oscillation and, from there, calculating the moment of inertia of the object.
Uses of Inertia Table:
- Determination of Moment of Inertia: Helps calculate the moment of inertia of objects with different shapes and mass distributions about a specific axis.
- Verification of Theoretical Values: Allows comparison of experimental results with theoretical calculations of moment of inertia.
How will you check that the base and inertia table are vertical? If not vertical, how will you manage that error?
Use a Plumbline: Hang a plumbline from a fixed point above the base of the inertia table. The string should hang freely and point directly downwards, providing a true vertical reference.
If you find that the base and table are not vertical:
Adjust the Legs: Many inertia tables have adjustable legs. Use these to level the table by screwing the legs in or out.
Shimming: If the table does not have adjustable legs, you can use shims (thin pieces of material) under the legs to level it.
How can the motion of inertia table of inertia be termed?
Motion of inertia table can be termed as angular simple harmonic motion.
