What do bicycle brakes do?
Bicycle brakes allow the rider to slow down in a controlled manner and with out undue wear on the tires.
What do the brakes do on a bicycle?
THey slow it down, if the rider so wishes.
Why are bicycle brakes a good example for a lever system?
Bicycle brakes exemplify a lever system because they utilize the principles of leverage to amplify force. When the rider squeezes the brake lever, it pivots around a fulcrum, allowing a small amount of force applied at the lever to generate a larger force at the brake pads. This mechanical advantage enhances stopping power while requiring minimal effort from the rider. Thus, the brake system efficiently converts the rider's input into effective braking action.
The first bicycle made in 1817 did not have what?
Brakes - the rider just put feet on ground to stop
What are two simple machines that are part of a bicycle called?
Two simple machines that are part of a bicycle are the wheel and axle and the lever. The wheel and axle allow the bicycle to move forward by rotating, while the lever system is used in the brakes and gears to increase or reduce force applied by the rider.
Why do keep moving forward when you slam on the brakes on your bicycle?
Because when you brake, the brakes stop the wheels from moving. But that doesn't stop the bike from moving. It means that the speed/force/velocity at which you were traveling was forceful enough to override the brakes. So basically, you're sliding.
How can a bicycle seat exert a force?
A bicycle seat exerts a force on a rider by supporting the rider's weight through normal force. When a person sits on the seat, their weight pushes down on the seat, and the seat pushes back up with an equal force (normal force) to support the rider.
How you would measure the mechanical advantage of a bicycle?
To measure the mechanical advantage of a bicycle, you would compare the input force applied by the rider to the output force produced at the wheels. The mechanical advantage is calculated by dividing the output force by the input force. In the case of a bicycle, the mechanical advantage helps determine how efficiently the rider's pedaling translates into forward motion.
What two controls on a bicycle can cause a change in speed?
The brakes, and the gear levers - assuming the rider keeps pedalling at the same pace.
How does the newton's second law of motion apply on a bicycle?
Newtons second law applies two bicycling because when your bike is going down hill, and you don't have to petal, your bike will not change direction unless you physically change the direction.
Where do you find friction in brakes of a bicycle brake?
A bicycle has high friction at the brakes, first and foremost. Then at places where the rider holds on to the bike, Grips and pedals. Between tires and road.
Would it be possible to harness the energy created by the friction of a bicycle tire?
Everytime the rider brakes, corners, or in any other way expose the wheels to a force different than the straight pull of gravity, the friction from the tires is harnessed.
