All you're doing is creating extra lateral forces. The average longitudinal force is still 8000N, and the average of the total lateral force of all 4 springs is still 0.

No. They reduce the force by increasing the length of time the impulse is applied to the occupants for. You can do that if you want, but it's the same old choice between 8000N for 1s, or 4000N for 2s. Neither gives any advantage.

springs are used throughout structual engineering and are
in use to reduce stresses.

Yes. But they also increase the length of time the parts are subject to that reduced stress.


Quote:

using the springs directs most of the force outwards
the stress that the pipe feels is outwards.

True, You're creating extra stress on the pipe walls without reducing the longitudinal force. It's effectively a lever mechanism.

It's still transmitting force to the ground through the fulcrum/pulleys. The total weight force felt by the ground is no different.
