Consider an elastic straight beam of length
L = 10n m, with square cross-section of side
a = 5 mm, and Young's modulus E =
GPa. This straight beam was bent in such a
200
way that the two ends meet, to form a circle
of mean radius R. Assuming that Euler-
Bernoulli beam theory is applicable to this
bending problem, the maximum tensile
bending stress in the bent beam is
MPа.
