Analysis
Plot
each of the graphs for the data you obtained from the experimental
measurements. Use this data to draw a diagram of the forces (where and in
what direction) which act on a stationary riderless bike and a stationary bike
with a rider. Discuss how these forces change as the position of the rider
changes. What would be the effect on your conclusions if the bicycle weighed
ten times as much? How does this information help you to decide on an optimum
rider position for cornering? If you were riding a bicycle on the moon, how
would your riding style need to be changed?
Consider a bicycle moving
in a straight line on a smooth horizontal road at a constant velocity. How
would the forces measured in your experiment be expected to change?
How
will the diagram of the forces on an inclined bicycle help you to understand
the forces acting on a
bicycle moving at a constant speed around a circle?
If Newton's Law, F = ma
(where F is a force, m the mass and a the acceleration), is applied
to the cornering bicycle, what would be the acceleration for a constant radius
(10 m) curve ? How is the force F related to the force F3 of your static measurements? |
