Hello - the balloon is a pressure vessel

the force of the car must be equaled by the force in the balloon pushing up.

Pressure equals force/area.

find the cross sectional area of the balloon (pi x radius x radius) - the max radius parallel to the ground.

Lifting half the car from the side use half it's mass x gravity to give the force.

This allows the pressure to be calculated

use pressure vesel calculations to find the stress produced in the material.
