It'll collapse unless the springs have enough stiffness in the longitudinal direction. They'll still carry the same load that way. They just might also carry a much higher load laterally as well.

There's no way you can arrange springs to make a component of the force dissapear. Imagine, if there was, you could lift a car with one hand. Just put this 'force redirecter' between you and the car, so its weight is sent sideways.

oh and you can use the accelerator to accelerate the
mass from 40 m/s to 0 m/s and that is also in the
(+) direction , and its ready to go again.

Then the mass is stopped so the machine can no longer operate??
