we should start a vehicle with neutral gear(0th gear). after starting shift to 1st gear so that to move the vehicle. when the vehicle is in 1st gear, it gets the power to start moving from the rest state. then , after attaining sufficient speed, change to 2nd, then 3rd, and so on. 1st gear gives more power, but less speed and top gears gives more speed, but lesser power. If we shift to top gears without attaining sufficient speed, engine starts knocking and the vehicle will be off within no time.
to gain more speed
No, the gear ratio is determined by the number of teeth in the ring gear and pinion gear. To be changed, that would require a physical alteration, which a speed sensor cannot do.
Aerodynamics, horse power, gear ratio,
Low RPM. Gear is too high for travel speed
Change up when ever you reach 2,000 rpm in any gear.
No, the wave speed does not change in the Doppler effect. The apparent frequency and wavelength of the wave change due to the motion of the source or observer relative to the wave, but the speed of the wave remains constant.
Double clutching, matching your RPM to the speed of the gear selected and doing it quickly, as most Scania trucks have a non-synchromesh gear system that will cause them to "grind" if you miss the speed or RPM or gear.
Not quite. The Doppler effect is actually the change in frequency or wavelength of a wave, depending on the relative motion between the source of the wave and the observer. This effect is responsible for phenomena like the change in pitch of a siren as it passes by.
Gear Cogs all move at the same speed, at the same time, just for moving one cog.
By using the "doppler" effect and measuring the change in frequency.
It can change its speed or direction.
a syncro is in the gearbox, it allows it binds up with a gear to allow the gearbox speed to become the same and the gear change to be smoothe
