Does anyone have any idea as to the typical torsional stiffness of a current or fairly recent F1 monocoque?
Yeah that would work for stiffness. If you consider the chassis as looking like a tube of certain radius (r) and thickness (t) from the front, the second moment of area is approximately equal to I=2*pi*t*r^3. So increasing the distance from the centre to the material, the higher the stiffness.NickS wrote:If the tub were of larger frontal X-section, would it be possible to increase its stiffness with no weight penalty? Or would the larger panels be too flexible? (i.e. Would it be possible to increase stiffness but only with a weight penalty by simply making the thing bigger?) Obviously there'd be a serious aero penalty....
Is there any chance you had the approximate weight for each style of chassis?Monstrobolaxa wrote:To give you a general idea of F1 development during the time here is more or less the typical values for diferent types of chassis/frame used in F1 during the years:
- Space Frame - 1000 lb/ft - 1356 Nm
- Lotus 25 frame (kind of space frame but with aluminum plates welded to the bottom and sides of the frame - 2400lb/ft - 3254,4 Nm
- First aluminum monocoques - 4500-6000lb/ft - 6102 - 8136 Nm
- First carbon monocoque (Mclaren MP4/1) - 14500 lb/ft - 19662 Nm
- Carbon fibre monocoques (nowadays) - anywhere between 22000 and 24000 lb/ft - 29832 - 32522 Nm
