 P: 1 [b]1. The problem statement, all variables and given/known data[We have a 5 litre rectangular fuel tank which when full of fuel will weigh 3.7kg, I need to simulate the affect off the car pulling 1.5g in the corner by tilting the fuel tank on the lateral and longitudinal axis. What angle would be required to achieve the same affect as 1.5g in a corner 2. Relevant equations [b]3. The attempt at a solution[I have tried working from inclined slope type problems in mechanics however this tends to have gravity as the resultant force , therefore the lateral force can't be 1.5g as then one side of the triangle would be larger than the hypotenuse.] There are two videos which show the rough type of rig I'm creating. http://www.youtube.com/watch?v=fv53RbvgfGc http://www.youtube.com/watch?v=fv53RbvgfGc Regards Richard Nash

Presumably you're just looking for the angle away from vertical of the net acceleration vector. If the 1.5 g acceleration is outward (horizontal) and the gravitational acceleration is always vertical, find the appropriate angle of the resultant.
