Although it's hard to tell from the photos, the car was a 1995 mustang convertible. The factor of safety is defined as the ratio of the ultimate yield strength to that of the stress generated in the roll cage. The roll cage system keeps the area around the driver intact.

First of all, we should say that the crash in question happened because the driver was engaged in a street race, aside from the fact that, if you are incapable of handling your car at extremely high speeds, you could end up hurting someone else. The impact test or crash test is performed assuming the vehicle hits the static rigid wall at. During fall the overall potential energy will be converted into kinetic energy hence;

Adding a roll cage would increase weight, reduce space, reduce fuel economy and increase cost. Here the factor of safety (fos) comes into picture. In the roof crash, you see the whole top of the cage crumble.

Roll cage is always a key factor to perform fea. Here's why we should all consider a roll cage for our next project car. , and also electrical system parts are mounted on the chassis frame.

Component for analysis is to study the behavior of the roll cage by simulating crash analysis in different impact scenarios. M*g*h=0.5*m*(v^2) v=√(𝑔)×ℎ×2 assuming the height of the fall. Impact test are performed on the designed roll cage.

A rollover can also occur as a vehicle crosses a ditch or slope. Static analysis of the roll cage is done using ansys workbench (static structural) for different collisions like front, side, rear and roll over. This was supplied by the f1 lotus team.
