Understanding Equilibrium and Torque

What is the state of a system in 2D equilibrium?

• The color of the objects

• The position of the objects

• The pressure of the system

• The temperature of the system

Which of the following is a method to maintain balance?

• Changing the color of the objects

• Adjusting the distance or weight

• Increasing the temperature

• Decreasing the pressure

What is torque?

• The ratio of distance to force

• The difference between two forces

• The product of force and distance

• The sum of forces

How can you balance a cup moved to a distance of 1/2D?

• By increasing the temperature of the system

• By changing the color of the cup

• By moving the other cup closer to 1/2D

• By adding more weight to the cup

If a cup is moved to 2D with a weight of 2W, how can it be balanced?

• By moving the other cup to 1/2D

• By decreasing the weight of the other cup to 1W

• By increasing the weight of the other cup to 4W

• By moving the other cup to 3D
