3 cards from this section. Quick, good the night before a test.
What does translational equilibrium mean?
Think about forces that balance each other.
Give an example of rotational equilibrium.
Consider a door that moves slowly.
What condition indicates translational equilibrium?
Think about the forces acting on a resting object.
True or False: An object in rotational equilibrium experiences angular acceleration.
Consider what happens to an object's rotation when in equilibrium.
A beam is supported at one end while carrying a weight of 200 N at the other end. What are the forces acting on the beam at equilibrium?
Consider the principle of balanced forces.
If a seesaw has a child weighing 30 kg on one side 2 meters from the pivot and another child weighing 20 kg on the other side, how far from the pivot must the 20 kg child sit for the seesaw to be in rotational equilibrium?
Use the formula for torque: torque = force x distance.
