Hey all Im a second year engineering student bored as hell in the second week of a 3 month vacation. So i decided to try and build a small railgun capable of launching a projectile(20-40g) to about 400km/h. Attached is a excel file. It is a sort of simulation. Cells in Blue must be typed in by user. Cells in Green list the Current/Mass needed to achieve desired values. The Cell in red must get its values from the table at a given point ( you choose ) This all makes alot more sense with the simulator. Please try it out! Any suggestions are welcome! Point out all the mistakes i made ( there must be a few ) and be critical please. This is a dangerous undertaking and i want to be as sure as possible about the math. Thank You!
