In a pulsating gas jet, the outside force in relation to the engine will be the force of the gas cyclic mass elastic interaction (Fig. 3) that arises at a definite combination of
Web30 jun. 2016 · According to the Newton's laws, the recoil force can be estimated as the time derivative of the momentum of the ablated material. We assume that the velocity of the evaporated atoms v is nearly constant in time and depends only on the surface temperature, so the Meshchersky equation can be used for the recoil force: (2) F = v m ˙ = v ℓ Λ 2 J. Web28 mrt. 2024 · Meshchersky asks for the CM speed as a function of height above the surface, rather than the vertical normal force. Both answers require calculation of the ladder angular speed, and are compatible.
