Concept explainers

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.

In this case, the applied force is always pulls upward, but the amount of force that can be applied can vary between 0-350 N (maximum). The locations of the applied force and resistance cannot be changed. Which of these statement is true? Select one: O The system could lift any resistance less than, but could not lift a resistance = 250 N. The system could lift any resistance that was 350 N. O The system could raise, but would be unable to lower a resistance.
