How do parachutes work?
The skydiver pulls out a pilot chute and releases it . The pilot chute then inflates and pulls the main canopy out of the pack, allowing it to open. This is how a sports skydiver opens his main parachute. Reserve parachutes are kept closed by a small pin holding a loop closed, and pulling a ripcord connected to this pin starts the deployment process. A spring loaded pilot chute is released, which inflates and pulls out the reserve parachute in a way similar to the main chute. This system is more reliable than the process used to pack the main parachute, but it is less convenient, and takes much longer to pack.
A 500-N parachutist opens his chute and experiences an air resistance force of 800 N The net force on the parachutist is?
300 N upward
When a parachute falls what is compressed?
When a parachute opens and falls, air beneath it is compressed in the canopy. The compressed air holds the chute open, and the open chute presents a large cross sectional area to the air in the direction it is moving (which is down). The large cross section of the open chute means that as it moves through the air, the whole area of the open chute will present a "front" to the air, and it will make it difficult for the air to move out and up past the chute (or make it difficult for the chute to move down through the air, whichever you prefer). The net result is that the chute and its load (a person, a cargo pack, or whatever) won't be able to move nearly as quickly through the air as the load alone without the chute for drag.If you wish to think through the problem and investigate further, you'll discover that the pressure in the chute is highest at the top in the middle. If a jumper opens his chute and a panel or two is blown out in some kind of failure, the jumper will have to make a decision about whether to cut away and open a reserve, open a reserve without cutting the primary chute away (and risking a tangle), or just riding the primary chute in with the blown panels. If the panels that have failed are in the sides of the chute, the incident is not as serious as if the panels that blew out are in the top. As the top is the higher pressure area of the chute, a blown panel is much more serious there as air at higher pressure is escaping through the chute (rather than out from under it and around it), and this will provide less "slowing" for the load on the chute. Again, think it through and consider what air is doing as the chute moves down through it and you'll be able to puzzle it out.
How does skydiving affect heart?
When free falling, you will experience high speed winds pushing against your body and it will feel like you are floating and not falling. You will feel a rush of air past your ears. There is some speculation that in the long term you may have some hearing loss. When the chute opens, you will experience 3-4 g's. This has no bad effect, but if you have back problems it can be a major problem. Another effect is just the pure excitement.
What do you do with the laptop on Club Penguin?
If you sit down while holding the laptop, it opens up.
Is there a trick to catching Pokémons on Pokémon pearl?
yes by pressing and holding 'A' when the poke ball opens
What is extreme about skydiving?
soon as you leave the plane you go from 0-200 kmph in 8 seconds then when the parachute opens. if it opens you got to figure out the winds to land go down wind on a windy you going pretty fast so there are some risks not really that extreme. try base jumping
Where can I get information on skydiving?
Common sense will explain the dangers of sky diving. If the parachute doesn't open, you die. If it opens too late, you die, or at the least, seriously injured. Power lines and water are also hazards if you land in them.
What force changes when a sky divers parachute opens what force stay the same?
The force down remains constant.force down (newtons) = (mass (kg) * acceleration due to gravity ((m/s)/s) ).The force up varies with velocity and drag coefficient ( which increases significantly when the chute opens).force up (newtons) = velocity2 * drag coefficient
What does skydiving feel like?
Skydiving is a great feeling and very much unlike a roller coaster. There is a gently sensation of floating. Yes you are going fast (around 120mph), but when strapped to a tandem instructor, it feels safe. This experience lasts for approximately 45 seconds before you feel a sudden deceleration as the instructor opens the parachute at around 5000ft. I thoroughly recommend sky diving as a fantastic adrenaline filled adventure.
How does a relief valve work?
Generally there's a spring holding the valve close, when the internal pressure is great enough, the valve opens - until the pressure drops. In some applications, there's a weight holding the valve closed.
Why does a parachutist have two terminal velocities?
Because the drag coefficient increases when the chute opens..Force down (newtons) = mass (m) * acceleration due to gravity (g)Force up (newtons) = velocity2 * drag coefficient.Terminal velocity is where up and down forces balance.Say mass (m) = 100 kg, g = 9.82, then force down = m * g = 982 newtons, say terminal velocity (v) prior to chute opening = 70 m / s, then force down = force up so 982 = v2 * drag coefficient, so drag coefficient = 982 / 4900 = 0.2without chute.Terminal velocity with chute open, say 8 metres / sec, so drag coefficient= 982 / 64 = 15.34 with chute open.
