How can drag be reduced when flying a plane?
Keeping the aircraft as light as possible. Having the centre of gravity as far back(aft) as the flight manual will allow. Flying at the minimum drag speed.
Does tension change in a parachute?
Yes: The force acting down is constant (mass * g) The force acting up = velocity 2 * drag coefficient At chute opening, the velocity is at its maximum, so up force due to drag is at its maximum. (maximum tension) Drag force reducing with diminishing velocity, to landing terminal velocity (minimum tension)
At what angle from a horizontal should a weapon be fired to achieve minimum distance traveled by the projectile?
Do you really mean minimum distance? This would be achieved if the projectile went straight up and down, ie 90 deg from horizontal. Maximum distance would be obtained at 45 deg to horizontal.
What are the forces acting on a skydiver?
Drag, I think? drag is good
When was Drag It Up created?
Drag It Up was created in 1999.
What is the minimum value of sum of a positive real number and its reciprocal?
This minimum is achieved when the number is 1 (and the reciprocal therefore is also 1).
The minimum altitude required for a satellite to avoid significant aerodynamic drag is?
200 miles(:
When water skiing if the boat was going fast would it create more drag or less drag for the skier?
The drag vs Speed graph will be a curve, with it's minimum at some speed greater than zero. At slow speed, the skier needs to angle the sji at a high angle to the water in order to produce enough lift to stay upright. This is known in Aerodynamics (and, I imaging, Hydrodynamics) as Induced drag. As the speed incearses, the skier can angle the ski at a lesser angle, thus reducing drag. However, as speed increases further, the frictional and drag forces associated both with the movement of the ski on the water, and the skier through the air increase ("Form and Parrasite" drag). The sum of all drag will reach a minimum where induced drag has reduced, but the other types of drag have yet to significantly increase. Drag will be greater at EITHER a slower OR faster speed than this minimum figure.

What is mellinium mode on a paintball gun?
It is a ramping mode that, as a minimum trigger pull speed is achieved, the marker rolls over into fully automatic for as long as minimum bps is kept.
Why did the Wright brothers achieve in flight?
I can tell you HOW: they used the forces of flight; lift, thrust, drag, and gravity That's pretty much WHY they achieved flight
Who designed the first airfoil?
In 1939, Eastman Jacobs at the NACA in Langley, designed and tested the first laminar flow airfoil sections. These shapes had extremely low drag and the section shown here achieved a lift to drag ratio of about 300.
By 1880 nearly three quarters of black southerners became what?
They became tenant farmers and achieved minimum autonomy through sharecropping.
Does tension change in a parachute?
Yes: The force acting down is constant (mass * g) The force acting up = velocity 2 * drag coefficient At chute opening, the velocity is at its maximum, so up force due to drag is at its maximum. (maximum tension) Drag force reducing with diminishing velocity, to landing terminal velocity (minimum tension)
How does downward forse help an Indy car?
When drivers always say they want more downforce in the turns, what they are asking for is maximum stickiness in the corners with minimum drag on the straights.
How much does a drag racer weigh?
In Pro Stock drag racing, the minimum weight for a car, including the driver, is 2,350 pounds. The NHRA Pro Stock racing champion for 2013 was Jeg Coughlin, and the person with the most NHRA Pro Stock wins is Warren Johnson with 97.
How many trust points have been given in total on WikiAnswers?
It would be impossible to say. (See the Related question for a list of contributors who have achieved a minimum of 2,000 trust points.)
