How to calculate the maximum acceleration that a tractor can achieve 3

[Explorer8888]

Generally, agricultural tractors have a speed limit of 40 Km/hr. Is there a way to calculate the maximum acceleration that tractors can reach keeping the maximum speed limit into consideration!!

 

[MintJulep]

a=T/mr

Knowledge of speed limit unnecessary.

 

[BrianPetersen]

Popping the clutch from a standstill with the engine at the governed limit will momentarily make it accelerate a lot faster than rated torque would indicate. Might even wheelie.

(I learned to drive on a tractor ...)

Highest acceleration would be a 40->0 stop in a short distance. Like within in the length of the vehicle.

Or ramming it into a solid metal wall... acceleration will be whatever you can get from deformation of a metal tractor @ 40km/hr.

OK, so what is the purpose of your OP?

That's easy. Strap a few JATOs on it; that's how the U2 takes off. I think Mythbusters used such a scheme to find out if a car could be launched into crashing to the side of a mountain.

The tractor can accelerate a towed load pretty smartly if you start with a lot of slack in the sturdy chain connecting them.

Max acceleration of 32 ft/sec^2 when driven off a cliff.

Way higher when it hits the rocks below ;-)

You are judged not by what you know, but by what you can do.

...in some frames of reference.

Negative acceleration.

Acceleration is normally a vector. Doesn't have a sign

Tell that to the tractor that came to a sudden stop

The tractor was never moving. The Earth hit it.

F = m*a

Figure out how much force (torque) the engine produces, Figure out the mass you're accelerating, and then the question remains basic as you solve for acceleration.

Don't forget to know the moment of inertia of drivetrain, how much friction you're dealing with, wind drag, and the fact that you would need a fictional transmission.

 

[Panther140]

Another good way to do it is put an accelerometer in the tractor, and then accelerate as fast as you can.

The first option I have you is somewhat like how an engineer would solve it.

The second answer is what the engineering technician would do when the engineer wants the actual answer ;p

I think he got sucked into a black hole. Calculate that acceleration.
