When may friction be desirable in engineering?
the brakes of you car are helped by friction.
What is desirable effect of friction?
The desirable effect of friction is that it allows us to walk, drive, and grip objects without slipping. This type of friction also helps us stop moving objects and control their speed.
When is friction desirable and undesirable in rugby?
Friction is desirable in rugby when players need to grip the ball, push against opponents in scrums or mauls, and maintain stability during tackles. However, friction can be undesirable when players are trying to move quickly or change direction, as excessive friction can slow them down or impede their movement.
What are the examples when friction is desirable?
Friction is desirable in situations such as driving a car (to maintain traction on the road), walking (to prevent slipping), and writing with a pen or pencil (to create friction against the paper for better control).
What is the example effect of desirable friction?
Very simply, desirable friction can be found on cars. Brakes are a good example. Another one is when you rub your hands together to produce heat. Striking a match is another and also uses a chemical reaction to produce a flame. All friction produces heat and many hundreds of uses have been found to utilise this heat.

Is frictional force desirable?
Frictional force can be both desirable and undesirable depending on the context. In some situations, frictional force is necessary for objects to stay in place or to prevent slipping. However, in other situations, frictional force can lead to loss of energy or wear and tear on surfaces, which may not be desirable.
What is an Example of low coefficient of friction?
One example of a material with a low coefficient of friction is polytetrafluoroethylene (PTFE), commonly known by the brand name Teflon. PTFE is a synthetic fluoropolymer that exhibits excellent non-stick properties and is widely used in applications where reduced friction is desirable, such as in cookware and as a lubricant.
Recognize the desirable and undesirable effects of friction?
Desirable: Stopping before hitting the car in front of you. Things stay in place during gentle breezes. Makes panning for gold possible. Keeps systems from oscillating out of control. Allows for climbing mountains. Allows for formation of stars and planets. Undesirable: Increases the amount of energy necessary to do any job.
Why is friction useful when using machines?
Just think if friction could not be obtained; your alternator would not charge the battery because the belt slips on the pulley. A car with a clutch would not move because the clutch slips. Friction is advantageous and desirable for some things and not for others. If we could eliminate friction, you would not need much gas to propel your car down the road. If you could not achieve friction with your lover, you would not achieve orgasm.
What is wanted friction?
Wanted friction refers to the level of friction that is desirable or required for a specific task or application. It is the optimal amount of resistance between two surfaces to prevent slipping or sliding while allowing for smooth movement or control. Achieving the desired amount of friction is crucial in designing systems or products for optimal performance and safety.
Is friction a friend or a foe?
Friction can be both a friend and a foe. It allows us to walk, hold things, and even write due to the grip it provides. However, friction also causes wear and tear in machinery and can slow down motion, which may not always be desirable.
