The first condition necessary to achieve equilibrium is that the system's net external force is:

  1. Exactly zero
  2. At a maximum
  3. Negative
  4. Twice as big
Show answer and solution

Correct answer: A. Exactly zero

1. Equilibrium is stated as a pair of conditions. 2. The first condition necessary to achieve equilibrium is already familiar. 3. The net external force on the system must be zero. 4. A second condition then deals with rotation. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 9 'Statics and Torque', sections 9.1-9.5_

For full equilibrium, alongside zero net force, what else must be zero?

  1. The total charge
  2. The net torque
  3. The total mass
  4. The total volume
Show answer and solution

Correct answer: B. The net torque

1. Balance requires both translation and rotation to be settled. 2. The net external force must be zero. 3. The net torque must also be zero. 4. Together those two statements define equilibrium. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 9 'Statics and Torque', sections 9.1-9.5_

The second condition for equilibrium involves avoiding:

  1. Accelerated rotation
  2. Any straight motion
  3. All contact forces
  4. Any change in mass
Show answer and solution

Correct answer: A. Accelerated rotation

1. The two conditions cover two kinds of acceleration. 2. The second condition necessary to achieve equilibrium involves torque. 3. It involves avoiding accelerated rotation. 4. That means maintaining a constant angular velocity. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 9 'Statics and Torque', sections 9.1-9.5_
