What is inertia?
Think of why a heavy object is hard to push.
Name the components of the equation of motion.
How many terms are in the equation?
What does 'm' in the equation of motion stand for?
Consider what is being resisted in motion.
True or False: Damping increases the amplitude of vibrations.
What is damping supposed to do?
Given a mass of 500 kg and a damping coefficient of 10 Ns/m, if the external force acting on a system is 2000 N, calculate the acceleration.
Use the basic equation of motion.
Explain how designing an earthquake-resistant structure changes when the mass of the structure is increased. Consider the effect on inertia forces.
