    Fuel Tank Test
AI Thread Summary
To simulate a 1.5g lateral acceleration in a fuel tank, the angle of tilt must be calculated based on the resultant of gravitational and lateral forces. The challenge arises from the mechanics of inclined planes, where the lateral force cannot exceed the gravitational force, complicating the triangle formed by these forces. The discussion suggests focusing on the angle of the net acceleration vector, which combines both the horizontal and vertical components. By determining this angle, the correct tilt for the fuel tank can be achieved. Accurate calculations are essential for effective simulation in the test rig.

1. Homework Statement [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



Homework Equations





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.

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.
