Question 1
What is the equation of motion for an undamped SDOF system?
- mx¨(t) + kx(t) = 0
- mx¨(t) - kx(t) = 0
- kx(t) = 0
💡 Hint: Remember, it describes mass and stiffness acting on displacement.
Question 2
True or False: Increasing mass will increase the natural frequency of a system.
- True
- False
💡 Hint: Think about how heavier masses respond compared to lighter ones.
