Hello. Could someone possibly help me with this question?
1. The problem:
The attatchment depicts a truck which has a centre of mass C.
• The truck is front wheel drive.
• The geometrical position of C is defined.
• The coefficient of friction between the tyres and the road is μ.
• Neglect the moment of inertia of the wheels.
The driver wants to find the maximum acceleration of the vehicle in the positive x direction.
Show the maximum acceleration of the truck is given by;

I have no idea how to do this question but here is my attempt at a solution:
[tex]\Sigma[/tex]Mb=0; mgb-Na(a-b)=0
[tex]\Sigma[/tex]Fy=0; Nb+Na-Mg=0
[tex]\Sigma[/tex]Fx=0; ah-[tex]\mu[/tex]h=0
and that's about where I'm at at the moment and I know I'm totally wrong! I would appreciate anybodys help.
