Question

I'm having trouble understanding this assignment. I don't even know where to begin. I'm not necessarily looking for direct answers, but some guidance/advice would be very much appreciated!

Using the speed ratio and the force ratio formula for a bike, design a bicycle that would be good at moving at high speeds on level ground.

Fill in the values you select:

# of teeth on front sprocket:

# of teeth on rear sprocket:

Radius of the back wheel:

Length of the crank arm:


What is the mechanical advantage of your bike?


If a rider turns the pedals of your bike at a speed of 2m/s, how fast will the bike move?

Formulas to use:

Mechanical advantage/force equation: crank length over # of front sprocket teeth multiplied by # of rear sprocket teeth over radius of rear wheel

Speed equation: # of front sprocket teeth over crank length multiplied by radius of rear wheel over # of rear sprocket teeth

Explanation / Answer
