Answer:
A. 0.0076 kgm²
B. The moment of inertia is the measurement of how much the object resists angular rotation.
Explanation:
Parameters given:
Mass, m = 0.6 kg
Length, L = 39 cm = 0.39 m
A. Moment of inertia of a rigid rod, I, is given as:
I = 1/12 * m * L²
I = 1/12 * 0.6 * 0.39²
I = 0.0076 kgm²
B. The moment of inertia is a property which measures an object's resistance to rotational acceleration about an axis (or more).
Therefore, it is a measurement of how much an object resists angular rotation.
Given Information:
Mass = M = 0.60 kg
Length = L = 39 cm = 0.39 m
Required Information:
Moment of inertia = I = ?
Answer:
Moment of inertia = 7.605x10⁻³ kg.m²
Explanation:
The moment of inertia of a rigid rod about center is given by
I = (1/12)ML²
Where M is the mass of rod and L is the length
I = (1/12)*0.60*(0.39)²
I = 7.605x10⁻³ kg.m²
We know that inertia is the property of all objects to remain in motion or at rest unless an external force acts upon it, in the same way moment of inertia is a property to resist the change in its rotation about some axis.
Therefore, the physical meaning of the moment of inertia is that moment of inertia is a measurement of how much the object resists angular rotation.
