one of our most exciting assignments - make something go around a 'moon' tht is to be powered by the springs of not more than 2 mouse traps of a typical made. tht's all the info given. ofcoz there's a complex equation describing how we'll get higher marks. we hav to maximize the distance travelled, maximize the return journey distance, minimize the error of landing pt, and minimize the left-behind mass. we can make 3 launches and the one with the maximum performance index will be recorded.


see the black spots on the rear wheel? they r actually calculations of wheel diameter, hehehe.

prepare to launch


this is the starting line, launching...10...9...8...7...


then, our vehicle 'old lady' is moving, on her way to the moon


discussion before the 2nd launch. we 'played save' on the 1st launch placing the 'moon' a bit nearer to 'earth' than the calculated and experimental distance 'old lady' can usually achieve. now, after having a reasonable result in the bk, we are going to go for the maximum usual performance.


vehicle of the other gp moving around the 'moon'(a 25cm diameter, 25cm height cylinder)


the reason it's called 'old lady' is bcoz it moves really slow, as we are pushing to the limit of the springs' energy to maximize our distance. afterall, speed of vehicle is not a factor in the performance index, hehehe...
