Because the fibers are aligned in the MD direction and consequently the sheet shrinks in the CD direction, resulting in a reduction in sheet width.

Why do you use fins and cone for a bottle rocket?
You use fins and a nose cone on a bottle rocket because the cone reduces the drag on the rocket, and the fins help stabilize the rocket.
What does the term drag mean in flight?
Drag is one of the four forces applicable to a flying aircraft: thrust, drag, lift and weight. Drag is the amount of resistance to forward motion caused by a solid body moving through a fluid (air is considered a fluid for the purpose of aerodynamics). The easiest way to feel the effect of drag is to stick one's arm out a car window while it's moving. First do it palm-down (horizontal), and then palm-forward (vertical). The force, known as "drag", pushing the arm backward increases substantially when the palm is vertical. That force is the same effect that an aircraft in flight experiences due to the frontal area of its airframe forcing its way through the air. The science of aerodynamics seeks to minimize the drag through streamlining and other design factors, since drag wastes fuel, but it is physically impossible to elimnate it.
How do you make a block movable using javascript?
search google for 'drag and drop script' OR go and download script.aculo.us, and implement the great drag and drop scripts they have.
What was the big hog drag line?
The big hog drag line was once the world's largest shovel. It was used for strip mining of coal in Drakesboro, KY.
Is copy and paste same as drag and drop?
No. Drag and drop is when you drag a file then drop it into the destination folder. You have moved a file from one place to another. Copy and paste is when you copy a file then paste it into a different location. The original file still remains where it was, but there is how a copy of it elsewhere as well.
Name the element of art which is a moving dot that has length and width?
Line. If you think of the tip of a pencil as the dot, and you drag it across paper, you get a line that can vary in both length and width.
What reduces drag?
Smoothness in the exposed surfaces of any vehicle is the main step to reducing drag.
How does an airplane prevent drag?
Aircraft design reduces drag, but cannot prevent it. Aerodynamics is the study of such.
Why do they close airplanes gear when it takeover?
the gear creates a lot of drag so raising it reduces that drag
How does streamlining reduce drag?
Force streamlining reduces air resistance or air friction.
Why is maximizing the ratio of lift to drag forces desirable?
engineers generally want a Lift to Drag ratio to maximize the distance which an aircraft can fly.
How does drag affect a paper airplane?
Drag effects paper airplane just as it affects anything else that moves. It is either parasitic or induced on paper airplanes. Drag may reduce a paper airplanes speed and/or range.
What does drag affect paper airplanes'?
Drag affects everything that flies.
What does drag mean?
Drag coefficient can be defined as the ratio of the drag on a body moving through air to the prioduct of the velocity and the surface area of the body.
What is the importance of lift to drag ratio?
In aircraft aerodynamics, the lift-to-drag ratio, or L/D ratio, is the amount of lift generated by an aerofoil, divided by the drag it creates by moving through the air. A higher or more favourable L/D ratio is typically one of the major goals in aircraft design; since a particular aircraft's required lift is set by its weight, delivering that lift with lower drag leads directly to better fuel economy, climb performance, and glide ratio.
What does drag coefficient mean?
Drag coefficient can be defined as the ratio of the drag on a body moving through air to the prioduct of the velocity and the surface area of the body.
What is increase column?
You could mean increase the column width, which just makes it wider. You can drag it out or set a fixed width.
