The beauty of a bicycle wheel design is that the spokes (narrow cylindrical wires connecting the wheel center to the perimeter) are loaded in tension, despite the compressive force exerted via the bicyclist's weight. Consider a stainless steel spoke with a diameter of 2 mm, under a 1000 N (224 lbf) load. (aThe beauty of a bicycle wheel design is that the spokes (narrow cylindrical wires connecting the wheel center to the perimeter) are loaded in tension, despite the compressive force exerted via the bicyclist's weight. Consider a stainless steel spoke with a diameter of 2 mm, under a ) What is the (tensile) stress on the spoke?
What is the elastic strain in the spoke, given that approximation of the stainless steel as a linear elastic continuum is a reasonable approximation? If the spoke is initially 25.50 cm long, what is the spoke length under the maximum applied load?
