Physics of Skydiving :: physics parachute skydiver sky dive

Could you bring in yourself jumping out of a perfectly good air cream off change of location at 170 MPH 13,000 feet above the ground? Imagine being the first person to jump out of an airplane, entrusting your life to an unproven go to technology. Over the past century, skydiving has grown from a madmans fantasy to a international sport.As a skydiver stands at the door of the airplane, the forces of their locoweed multiplied by temperance is directly countered by the force of the plane pushing binding up on their feet, this is know as the prevalent force and is shown is the equationFN = m * gAs soon as the the diver exits the plane, the normal force is removed and the diver begins to fall. Generally, a skydiver forget exit the airplane at about 13,000 feet (4000 meters). To chief(prenominal)tain a persistent flight, their body must face the relative wind. This is the direction in which the greatest air resistance is coming from. After a jump shot exits, the train forc e of the air counteracts the jumpers horizontal motion until the drag is completely working against gravity. For a 70 kg jumper with the acceleration of gravity (9,8 m/s2), the force of gravity can be calculated with the resembling equation as the normal forceFg = 70 * 9.8 = 686 NewtonsThe force of the drag ca exampled by particles of air is calculated by this equation withFD=1/2 * CDr * v2 * AFD force of dragCDr coefficent of dragv velocityA surface area of the jumperWhen we set the FD equal to the Force of gravity on the diver and use the drag coefficient for the density of air and use the area of a diver in the arch position we observe that the diver find a balance of forces (no acceleration) at about 55 m/s. When a skydiver wants to deploy their parachute, the most commonly used twisting used is a manually-operated pilot chute. The diver will reach back into their rig and grab a handle or lower-ranking garret bag connected to the pilot chute and throw it away from them.T he small pilot chute is affected by an extra drag force attempting to keep it stationary. When this force and the force of the falling diver create comme il faut tension in the line connected to the pilot chute, the deployment bag containing the main canopy is unstowed.If the main canopy were to expand to full size immediately, the plastic forces between the diver and the main canopy would most likely charge the diver and/or break the lines.
