How to use a computer for engineering problems Engineering Problem: Design the suspension of this car. Performance measure is the amount the passenger will get displaced (bounced) up and down as the car travels. Step 1: Think like a physicist. A suspension is complicated. Come up with a simpler physical system that captures essential features. Step 2: Think like a mathematical physicist. To understand the simpler physical system without building it, develop a mathematical model of the simpler system. Step 3. Think like a mathematician. Figure out a method to solve the mathematical model, e.g., get the displacement of the passenger given the depth of the potholes. Step 4. Think like an engineer. Compute the model for different values of spring stiffness, damping coefficient, and mass until you find values at which performance is okay and the system can be built. Step 5. Build and test……….

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
