The fan-belt and tires of a car.
The formula for calculating the work done by friction is: Work Force of friction x Distance.
No, velcro needs friction to function properly. The hooks and loops on velcro fasteners grip each other when pressed together, and this requires friction to create the necessary force for them to engage and hold together. Without friction, the hooks and loops would not interlock securely.
In a hydraulic device, the work done by the input piston will be equal to the work done by the output piston if the system is ideal and there are no energy losses due to friction or other factors. This is based on the principle of conservation of energy in a closed system.
The force of friction needs to touch an object to have an effect. Friction occurs when two surfaces are in contact and one surface resists the motion of the other surface. It is this resistance that allows friction to have an effect on objects in contact.
No, more friction does not necessarily mean more work. Friction is a force that resists motion, but work is defined as the product of force and displacement in the direction of the force. So, while friction can make it harder to do work in certain situations, they are not directly proportional.
On her feet and hands. That is why they build climbing shoes from sticky rubber. Her belay partner will need friction in their belay device (ATC OR GRI GRI, etc)
Yep. This is because the device needs the battery in order to work.
Yep. This is because the device needs the battery in order to work.
No, an electric device will not work if the power cord is not attached as it needs the electricity provided by the cord to function. Without the power cord, there is no source of electricity to power the device.
Tires, grips, pedals and brakes needs to have high friction, while all rotating parts needs to have low friction.
Fluid friction.
The formula for calculating the work done by friction is: Work Force of friction x Distance.
Because the device needs their electrical properties in order to work.
Probably, yes. Providing more power than a device needs is seldom a problem.
No, velcro needs friction to function properly. The hooks and loops on velcro fasteners grip each other when pressed together, and this requires friction to create the necessary force for them to engage and hold together. Without friction, the hooks and loops would not interlock securely.
No, We cannot do work on friction less surface
