(Re-) Introduction to Working Model - The falling meterstick This lab introduces/re-introduces Working Model. The goal is to create a simulation of a meterstick which leans against a wall and the floor, both of which have various static and kinetic coefficients of friction, as it rests at different angles with respect to the horizontal. Note: This lab file is required for lab 04 - make sure you have a copy of it before leaving class! |

MSD Energy Lab - The translating cart Here we demonstrate conservation of mechanical energy by first compressing a spring, then allowing the spring energy to be transferred to a mass-laden cart. Simulink real-time-workshop gives us a clean software interface with the hardware dynamic system. Applying basic principles we can explain why the lighter cart moves faster, and why it is unwise to drag-race with an empty Duramax diesel Chevy! |

MechSys Final Four - The swinging pendulum As we are beginning to see, mechanical systems are a somewhat non-intuitive endeavor - our gut feelings may lead us astray. This lab will investigate a swinging pendulum with an attached, movable weight. We will begin by guessing the placement of the weight for the fastest angular velocity (competing for valuable cash and prizes!), then model the system with working model, and then develop a closed form solution using the principles of mechanical systems. |

MechSys Final Four - The swinging pendulum part deux Use the precisely instrumented hardware in the Controls lab to measure the precise time of swing for a small scale pendulum with moveable weight. See how well your experimental result matches the theoretical found in homework set 5. It don't mean a thing if it ain't got that swing! |

| L-03 |
Experimental vs Numerical vs Exact - The falling meterstick part deux This lab investigates how we model the coefficient of friction for a simple bar as it slides down a wall. You get to make big smeary blotches on the board to obtain experimental departure points, build a model in working model, and solve the problem exactly. Note: This lab file is required forYou ned your WM file from lab 01 plus hwk 24.1 for this lab |
