Expert Solution

A.The torque produced by a force takes the form of a vector product.

Torque is a measure of how much a force acting on an object causes that object to rotate.

B Angular acceleration, also called rotational acceleration, is a quantitative expression of the change in angular velocity that a spinning object undergoes per unit time. It is a vectorquantity, consisting of a magnitude component and either of two defined directions or senses.

oment of Inertia (Mass Moment of Inertia) - I - is a measure of an object's resistance to changes in rotation direction. Moment of Inertia has the same relationship to angular acceleration as mass has to linear acceleration.

For a point mass the Moment of Inertia is the mass times the square of perpendicular distance to the rotation reference axis and can be expressed as

I = m r² (1)

where

I = moment of inertia (lb_m ft², kg m²)

m = mass (lb_m, kg)

r = distance between axis and rotation mass (ft, m)

Consider the four definitions of information presented in this chapter. The problem with the first definition, “knowledge derived from data,” is that it merely substitutes one word we don’t know the meaning of (information) for a second word we don’t know the meaning of (knowledge). The problem with the second definition, “data presented in a meaningful context,” is that it is too subjective. Whose context? What makes a context meaningful? The third definition, “data processed by summing, ordering, averaging, etc.,”...
