| L-01 | Introduction
to Working Model - The falling meter stick simulation in Working
Model This lab introduces Working Model. The goal is to create a simulation of a meter stick 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. |

| L-02 | Swinging Pendulum simulation
in Working Model
- 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. |

| L-03 | Swinging pendulum experiment
in the controls lab
- 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 simulation results from Lab 02 and the theoretical results found in homework set 5. It don't mean a thing if it ain't got that swing!

| L-04 | Crane problem simulation in
Working Model
When using an overhead crane to move a load, it might be wise to design the crane such that it reaches its intended destination with minimal residual swing. You will build the Working Model that will help you discover the secret of killing the swing! |

| L-05 | Crane problem experiment in
the controls lab - Using the Controls lab hardware, determine where to place the moveable weight such that swing is minimized when the overhead crane comes to a stop. See how well your Working model prediction and the analytical solution match the actual performance of the hardware. |
