    I know this is obvious but it boggles my mind how each square inch of that tire has almost 100lbs of force pushing on it

    Just realizing now why hydraulics are so strong, a 6 inch squared piston at 100 psi is 600 pounds of force

      If you consider that a car weighs hundreds of kilograms but its contact surface with ground is something like 100 squared centimetres, that pressure makes sense

      I work with industrial hydraulics, the forces involved in big gear are truly insane.

      Working pressures is around 270bar…on ~1.4m^2 of cylinders. Millions of kg of force.
