How does a streamline shape reduce drag?
streamlining, in aerodynamics, the contouring of an object, such as an aircraft body, to reduce its drag, or resistance to motion through a stream of air. This eddy formation represents a reduction in the downstream pressure on the moving object and is a principal source of drag.
How does streamlined shape reduce friction?
It reduces the drag. It is the air/water resistance offered when you travel through it. With a streamlined shape, the area of the body that pushes air/water becomes very small. This is how making a body streamlined helps cut through the drag.
What is streamlining in friction?
Streamlining is a design that offers the least resistance to the flow of liquid. Friction is minimum for the streamlined shapes, which is generally rounded in the front and narrow at the back. The bodies of rockets, cars, aeroplanes are streamlined to reduce the friction with the air.
How can we reduce friction?
Methods for Reduction friction:
- Make the surfaces little more smoother.
- Lubrication is another way to make a surface smoother.
- Make the object more streamlined.
- Reduce the Normal force acting between the surfaces in contact.
- Reduce the contact between the surfaces, so that less number of bonds will be formed.

What is streamlined shape how it is useful?
A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. For aeroplanes the surface is having streamlined shape and for ships also in the water to reduce the fluid friction.
What does streamlined shape mean?
A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. It offers a minimum resistance to air and water by its particular type of body shape .
How can you reduce friction?
How do lubricants reduce friction?
Lubrication reduces the heat generated when two surfaces are in motion. It smoothes the process by forming a film between two surfaces that reduces friction and thus improves performance and efficiency.
What is the most common way to reduce friction?
By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.
Why do we reduce friction?
Why do we need to decrease friction? Friction is a necessary evil which causes a lot of wear and tear in machine parts that move against each other. It erodes the surfaces and destroys their symmetries. Hence, in such cases it is desirable to reduce friction.
