The minimum theoretical stopping distance of a fork/lift truck traveling at 16km/hr is 8.5m. however tests have shown that if it stops that quickly it will weither lose its load or tip forward and in fact the minial stoppping distance is 10m. Therefore:

a) explain why a suddent stop will cause the load to shift forward and why the whole truck may tip at the same time? and

b) explain why it is dangerous to drive a fork lift truck with its load raised use equations.

ok lets see... A) I think it was Newtons law : An object in motion will stay in motion unless acted apon by an outside force. something like that

and B) I dont know the equation but Center of gravity his raised with the load higher causing it to be able to tip easier

A) Newton got this one right - any object that is in motion will tend to stay in motion unless acted upon by an opposite force. In other words, that load is going to try and keep going even if the fork lift is stopped suddenly.

B) The center of gravity is the key to this question. The higher the center of gravity, the less stable the device.

1 The load is not attached to the truck.
2 The center of gravity is like a pyramid between the drive wheels and the middle of the steering axle. I more weight is outside of it it'll flip. F=force D = distance FxD= FxD the higher the mast the higher the distance D.

I've driven forklifts for ten years now and physics aside you dont drive with your load raised because you center of gravity is altered and when you stop your load rate will create such force that the counter weight will be too little causing you to tip forward,I've done that (not fun!)the best I can tell you is its similiar to those scales that work on counter weight like the one the justice lady holds. Go and see if you canfind somewhere you can drive a forklift and you'll find out!
