Question

A steel beam can be cut to different lengths for a project. Assuming the weight of a

steel beam is proportional to its length, what information would you need to know
to write an equation that represents this relationship?

Answer 1

L = length of beam (known)

LS = length of sections to cut (unknown)

W = weight of beam (known)

WS = weights of sections to cut (known)

W/WS = L/LS
