Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.

Determine the following statement that is true regarding Mohr's Circle. Reference points on Mohr's Circle from two perpendicular axes on the cross-section can lie at angles smaller than 180 degrees relative to each other. Mohr's Circle can't be used to identify angles between principal and non-principal axes. Mohr's Circle contains all possible moment of inertia and product of inertia values for a given fixed area about all rotated axes around the same origin. A reference point on Mohr's Circle that corresponds to one of the principal axes can lie at coordinates of (492, 18.7). The center of Mohr's Circle can only be calculated using principal moments of inertia.
