The impulse supplied by the counterweight equals the loss of horizontal momentum of a jet of water. The exit velocity of the water jet is then calculated and checked by measuring range. 1N10.63 thrust with air carts 9-4.6 Two carts, one with an air nozzle, the other with a reversible hemispherical deflector can be connected by a spring to show forces internal and external to a system and the effects on thrust resistance and thrust reversal. Using solid fuel model rocket engines as an impulse generator, demonstrate the impulse-momentum theorem by measuring the final velocity. A device provides a method of measuring the thrust of a model rocket engine and recording it on graph paper.
Impulse is calculated.
1N10.72 model rocket thrust 9-3.1 Modify a toy rockets to maintain continuous discharge. Attach to a platform scale. 9-3.5 An apparatus designed to measure the thrust of a rocket is used to check the manufacturer's specifications. Speed and acceleration are determined by strobe photography. A rocket pendulum maintains the same angle of recoil in air or water showing thrust is independent of medium.
