Distribute an egg or water balloon to each pair of students and challengethem to find a surface outdoors to drop their item on from a height of one meter while trying to keep it from breaking. 5.
This is done through the force exerted on the egg by the ground (the impulse). Step 3/5 3. The key difference between the concrete and the sponge is how quickly this force is applied. On the concrete, the force is applied almost instantly, causing a large amount of pressure on the egg and causing it to break. Step 4/5 4.
The impulse load resulting from jet impingement is localised to the affected area. Pipe whip restrain action. Postulated breaks in high-energy piping, which result in the escape of fluid or gas from the pipe, will induce motion to the pipe.
