Using a magnetic Dynamo on a bicycle at the rear rim or the front rim. A magnetic Dynamo produces D.C (direct current) due to magnetic induction, this can be used to power a b…ulb on the bicycle. The two magnets do not come in contact as htey are separated by some distance and as the cycle gains speed the revolutions of the tyres become faster and the amount of current generated is directly propotional to the RPM( revolutions per minute).Therefore the intensity of the bulb is not consitent if the speed of the bicycle is not consistent. Magnetic Induction: When one magnet is moved to and fro with respect to another magnet with opposite facing it (the distance has to be short) with a good frequency, it produces current opposite to the direction of the moving magnet. This is because the magnet field strength (intensity) changes with respect to the distance between the two magnets. This changes in turn produces current. (MORE)

Basically, as a body accelerates, the forces acting upon it are unbalanced. However, as one reaches uniform speed (constant speed) you are no longer accelerating, so the force…s acting upon the bike are now balanced. Newton's second law of motion states that when something is moving, it will continue to move at the same velocity until another force is applied (inertia). Because of this, the bike will be moving "on its own" after you stop peddling, so there is less need to pedal. (MORE)

because the muscles in your arms pulling on the handle bars causes an equal and opposite reaction from the bars acting on your arms in a direction toward the bike. this force …counteracts some of the upward force from the equal and opposite reaction from the pedals due to you pushing down with your feet. in other words, it allows you to counter some of the force by involving muscle from your arm in the force to hold you down to the bike. You are using the muscles in your arms to pull your weight downwards on the pedals with a greater force than just using your legs alone. You are using your legs and arms in tandem to pedal. (MORE)

Yes it was possible. Emperor Napoleon III died in 1873 and the pedal bicycle was invented in 1839.

All you must do is multiply 0.10 km by the number of minutes in the given time, in this case 120. She will go 12 km.

There's no way of telling, as that would depend on the wheel size and gear ratio, which can vary from bike to bike. The Online Gear Calculator (in the relevant links se…ction below) is very useful for calculating the distance traveled on a single pedal stroke, if you have some parameters to input. (MORE)

Either 15mm or 9/16", or it can take a hex(allen) key at the face of the axle instead. Remember that the left side pedal has a counter-clock thread.

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4
