Develop a general formula that expresses the pedal height (in cm) of a bicycle as a function of time (in sec.) at a constant speed.
Take into account:
· wheel circumference in cm
· speed in km/h
· gear (number of teeth at the front and number of teeth at the back)
· length of the pedal rod in cm
· height of the pedal axle in relation to the ground in cm
· starting position of the pedal
· left or right pedal
