Question

A bicycle chain consists of a series of small
links, where each are 12 mm long between the centers
of the pins (see figure). You might wish to examine
a bicycle chain and observe its construction.
Note particularly the pins, which have a diameter
of 2.5 mm.
To solve this problem, make two measurements
on a bicycle (see figure): (1) the length L of the crank
arm from main axle to pedal axle and (2) the radius R
of the sprocket (the toothed wheel, sometimes called
the chainring).
(a) Using your measured dimensions, calculate
the tensile force T in the chain due to a force
F = 800 N applied to one of the pedals.
(b) Calculate the average shear stress τ_aver in the pins.
