- is it better to use a AUTOMATIC gear transmission system(and where can i find such a thing that is small enough) or just 1 fixed gearset?
- is it better to have a heavy car and go a bit slower, then having a light weighted car and go a bit faster?
-what is the best in this situation, front wheel driving of rear wheel driving.
-is it possible to store some energie the first 10 seconds and then release it in the 10 last second while the motor gives an extra boost? is their a system for this? anny ideas?
any response, idea or comment is welcome.
a few details:
the dimensions of the solar panel are 18 cm broad and 36 cm high.
the dimensions of the car are 35cm X 60cm X undefined
the motor use (don't have thedetails and calculation results jet) wil run at 1600 rpm
the car has to drive in a straight line between two walls that are places 35cm from each other
we have to make or buy everything, pick wheels, build the base, gears,...
What is your formula for Kinetic energy? That will answer your second question.
Double the weight or double the speed? which will give you best KE?
KE increases as the square of speed, so light and fast is better.
Rear drive always gives you better traction when accelerating as weight shifts to the wheels, not away from them.
Is it a single solar panel? Volts? Watts? this will determine your range of motors to use, also what time of day will you run the test? angle of the sun, best angle to mount the solar panels. Lots of variables.
