Proposal Writing Assignment

A methodology for converting the strain gage data to the reading of power This is a proposal on a methodological development that offers an insight on how to establish a power meter that shall be attached to the bicycle’s crank arm. Designed in such a manner that it allows for a signal transmission into an operating system at the ultimate rate of about 10,000 times/second (Gunn &amp. Jack, 1955). This wireless strain gage is deemed to be utilized in determination of the real time power that is transmitted by the cyclist to the entire bicycle. The primary application of this model is for the athletes to come up with the most favorable training schedules. These kinds of schedules tends to eliminate the gauging exercise intensity guesswork, improves the quantitative tracking with regards to the fitness levels, helps in defining an individual’s weaknesses, acts as an effort monitor, as well as a proper perspective for aerodynamic position testing.
Many cyclists often produce equal power output from both legs. The Info Crank tends to measures independently even small variations between the left and the right leg. A host of the remedial measures often exist to with the ultimate role of correcting the asymmetrical power inputs that requires adequate measurements. Info Crank will thus act as an accurate power meter with regards to cycling. Accuracy can hence be taken as an unlimited value that is accurate to almost 5 Watts. The relative measurements, as well as the cycling power readings should have greater reference on the context of ±2% regarding the systems utmost reading capability (Krolop &amp. Pfeffer et.al, 368). The level of accuracy also sets basis on the measurement of cadence, as well as the A-D converters rates of sampling. There is hence little or no variation between the amounts of watts deliberated on a single Info Crank’s set. If the Info Crank is switched between bikes, the measured watts are often equal.
Power is basically a phenomenon that has to do with the aspect of force and velocity. The mathematical expression can be taken as: power (W) = force x distance / time. Watts on the other hand refers to energy that is needed to move a given mass to a particular distance within an identified period of time. In short, is taken to be 1W = 1Nm/s. So in a bike speak, the overall mass will be taken as the sum of that of the cyclist plus that of the bike, while the distance should be taken as the covered ground distance. There is some difficulty when it comes to the measurement of power due to the resistance brought out as a result of inconsistent motion.
So, given that power is equivalent to force x distance / time
and, displacement / time = velocity,
Then the overall equation can thus be taken as.
power = force x velocity (Gunn &amp. Jack, 1955).
This is thus the key towards understanding the way a power meter operates. It is essentially the matter of applying this kind of equation to a part of a bike, ranging from the BB axle, hub, crank, and pedal axle, among others. This is a situation whereby the movement speed or the angular velocity can be measured and multiplied by the amount of the force computed by the strain gauges (Krolop &amp. Pfeffer et.al, 371).
