What are the action and reaction forces on the fabric of a parachute when it is deployed?
When a parachute is deployed, the action force is the air resistance pushing against the parachute fabric. This air resistance is created by the change in the air's velocity as it passes through the canopy of the open parachute. The reaction force to this action force is the drag force created by the parachute pulling against the jumper. This drag force is created by the increase in the parachute's surface area, which slows the jumper down as they fall. The drag force is also responsible for the parachute's ability to slow the jumper's descent enough to safely reach the ground.
What does parachute mean?
A device, generally constructed from fabric, that is designed to employ air resistance to control the fall of an object; To jump, fall, descend ...
What is the difference between ironing and pressing?
Ironing - Ironing is just an action moving back and forth on the fabric Pressing- Pressing is used to flatten and area that has been stiched
What is bowing percentage in fabric?
how to get the percentage of bowing fabric
How does a color of a fabric affect its temperature?
If the fabric color is dark then it absorb heat from the sun and the fabric's temperature will rise.

Can you use parachute fabric on the moon?
There is no air in the moons atmosphere so a parachute would not open.
Why are the gores on a parachute cut out in triangles and sewn together across the fabric?
Logically I would think that it's for practicality of the dimensions of the bulk fabric, and strength. A round parachute is a fairly simple machine, though there are many variations. Martin Myrtle www.aircapitaldropzone.com
Is tin foil good for building a parachute?
Possibly, but tin foil is rather fragile, and easily torn. A cotton or silk fabric would make a better, more resilient, parachute.
Why can astronauts not use parachutes to help slow down their spacecraft?
The fabric of the parachute would catch on fire as they made contact with the atmosphere
What do you use to make air puppets?
You would need fabric (nylon is best, a.k.a. parachute fabric) Cut out your puppet pattern, double stitch the fabric together. Then you need a fan, or some other type of air or wind blowing device, and a light.
How does urea affect dyeing of fabrics?
Urea helps the dye penetrate the fabric. Moisture is an important component of the chemical reaction process with dyes, and urea helps draw moisture to the chemical reaction. Urea also helps to keep the fabric damp long enough for the reaction to occur.
How does a plant get water from its roots?
By a process called CAPILLARY REACTION - it's similar to dipping cotton fabric in a bowl of water and watching it creep up the fabric against gravity
What happens when you bleach white cloth?
The effect is that it does make it weaker by stretching and sweaping the fabric
What material do they use in parachutes?
Parachutes are most commonly made of nylon. The term "ripstop nylon" used to be applied to the construction materials, but any more, it is "nylon" from which almost all chutes are made. During WWII parachutes were made of silk as nylon wasn't around yet.
The materials to make a parachute?
You will need: Ripstop nylon fabric for the wing Nylon thread of various weights for sewing Polyester cord for the lines Steel hardware for the links Nylon webbing for the harness and risers
What does the quote 'Minds are like parachutes They only function when open' mean?
An open mind is a mind that is non-judging, open to new thoughts, ways of doing things. That does not see obstacles but opportunities. Before you think about the meaning of this quote, you need to be clear of some terms that seem to be quite obvious, but they aren't:* What is a parachute? * What is mind? * What is the difference between a closed and an open parachute This brings us to the question: What is an open mind?A parachute is usually a soft fabric device used to slow the motion of an object through an atmosphere by creating drag.Mind collectively refers to the aspects of intellect and consciousness manifested as combinations of thought, perception, memory, emotion, will and imagination An open parachute is obviously "in action" or "used" and function, while a parachute is closed when not in use.The quote "Minds are like parachutes[...]" means that there can be a functional and disfunctional mind (compared to a closed and open parachute). Tommy Deware, who is the author of this quote, states that only an open mind is a mind that is really functioning.You can make your own sense to what an open mind is (see also previous answer).
