Challenge Problems
Push your limits with challenges.
Question 1
A control system has an input that is turned on at t=3 seconds and remains on indefinitely. Describe how you would model this using the unit step function and derive the Laplace Transform.
💡 Hint: Start by writing down what happens at the time 3 seconds.
Question 2
You are given a mechanical system that each force is applied suddenly at intervals of 2 seconds. Explain how you would set up the differential equation using the Laplace Transform and the unit step function.
💡 Hint: How does the forces’ sudden application affect the system's motion?
