Automatic gear changing system

  1. Nov 8, 2012 #1
    if we keep a spring attached to a trolley on moving vehicle we find the force by f=kx and the potential energy by 1/2kx^2. thus we calculate the friction, the slope of the road and device an system to automatically change gear.we already know the petrol consumed, speed and acceleration and mass of the vehicle.

    Is that a question?
    There are automatic transmission systems, and they are quite common today.

    The early systems were really bad, too, changing gear just when you didn't want to and not doing it when you needed it most. Modern automatic boxes are very sophisticated and you will not achieve anything as good as that without a lot of knowledge and research.
