- Homework Statement
- 85. Assume a cyclist of weight mg can exert a force on the

pedals equal to 0.90 mg on the average. If the pedals rotate

in a circle of radius 18 cm, the wheels have a radius of 34 cm,

and the front and back sprockets on which the chain runs

have 42 and 19 teeth respectively (Fig. 31), determine the

maximum steepness of hill the cyclist can climb at constant

speed. Assume the mass of the bike is 12 kg and that of the

rider is 65 kg. Ignore friction. Assume the cyclist’s average

force is always: (a) downward; (b) tangential to pedal motion.

can I get some tips on how to approach this problem ? I don't get where I should start on this one.
