What is the coefficient of friction for bicycle tires?
twice as much as half of it!
How is friction helpfull?
Friction is helpful so you dont fall and friction helps things work much better than others. friction can also be helpfull when someone is driving. for an example on a slippery road frictio between the tires and the road stops the cars from sliding off the road and crashing. In sports friction stops the ball from going on forever. without friction we would just keep going on and on with out stopping. friction helps stop a bicycle from going on forever when we push the brakes in a bicycle it creates friction, which slows us down to a stop.
Can car brakes overheat?
Yes, they can. It tends to happen more rapidly in heavy duty vehicles with air brakes, but it can happen in light duty vehicles with hydraulic brakes, as well. Brakes create friction, friction creates heat. Too much of it, and they overheat.
What caused brakes to go flat down when mash?
It could be air in the brake line, or the brakes getting too hot from too much friction by using the brakes on a steep hill or riding the brakes, or there could be a problem with the master cylinder.
Is friction useful when you are on a slide?
if there was no friction on a slide, you would gain speed and slide off and depending on the slide (such as a water slide) kill yourself. too much friction makes it boring.
How does properly maintaining your bicycle increase its mechanical efficiency?
If it wasn't properly lubed before, then efficieny will be improved by lubricating. If it was properly lubed before, nothing much will happen.
What is the different between istatistic and kinetic friction?
I assume you mean static and kinetic friction. Static friction tends to be stronger and less predictable. For example, if you start applying more and more force to a stationary brick lying on sandpaper, it is almost impossible to predict when it will begin to move. Once it is moving, however, you can get a pretty consistent estimate for how much drag the brick is experiencing (kinetic friction). Modern cars have computers monitoring the brakes. If you slam on your brakes, the computer will loosen up the brakes to prevent you from skidding. This is because static friction is more effective than kinetic friction, and once you start skidding out you have lost most of your braking power.
What in the world is weight weenies?
"Weight weenies are a list of how much different bicycle parts weigh. This may include the brakes, wheels, frame, seat, etc..."
How do you connect the hand brakes on huffy bike?
Too complex to answer here. Have a look at www.parktool.com, www.sheldonbrown.com or www.biketutor.com and read more.
Where is friction not helpful us?
friction is not useful when;involving engines because you will be losing alot of energy.when sliding across the room with a wheel chair because it will be much slower and difficult
Vehicle starts to skid you should trun steering wheel?
RELEASE THE ACCELERATOR FIRST, then turn...do not apply the brakes this is because the ability for your car 2 steer is dependant on the friction between the road and tyres. if u apply the brakes u risk at locking them up. if this happens there is nearly no friction and u wont b able 2 make the turn. what u want to do is to use as much of that friction solely 2 turn the car...hence u should not use the brakes
Is friction always something we want reduce?
NO!You very much need to increase friction between car tires and the road surface in winter. Accumulated snow and ice can already reduce friction there to the point that stopping and steering the car becomes impossible leading to many severe and occasionally fatal accidents.Vehicle brakes also need as much friction as possible to efficiently stop the vehicle when needed.Sandpaper and other abrasives depend on friction to smooth and clean surfaces.etc.
