F.1.1 Chassis

Explanation

The chassis is the frame of the car. Every car that drives on the road has a chassis, but they look a little different than the FSAE chassis we use. For our purposes, think of the chassis as a giant bracket, holding all of the other components together. The way we design the chassis will be constrained by not only these rules, but also our suspension nodes. The chassis will also have to accommodate all of the car's components. This means the chassis design will have to be completed last, because it will depend entirely on how all the other components have to fit in the car. 

Here are some examples of chassis on normal cars, and FSAE chassis: 

One of the most important functions of the chassis, is to be torsionally rigid. Torsional rigidity is the ability of an object to resist twisting when acted upon by an external force or torque. The chassis needs to be as rigid as possible, because suspension calculations can not take the chassis displacement into account, so it is important to minimize chassis displacement.
