he shaft of a belt drive is made of AISI C1020 as rolled steel. The belt tensions vary continuously during transmission at a constant tension ratio of 3:1; the maximum tight side tension being 400 lb and the minimum tight side tension is expected to be 160 lb, at a pulley diameter of 12 inches. For a Goodman factor of safety of 1.8, recommend the diameter of the shaft. Consider a machined surface and the effect of a hardened profile keyway in the shaft.

Question

The shaft of a belt drive is made of AISI C1020 as rolled steel. The belt tensions vary continuously
during transmission at a constant tension ratio of 3:1; the maximum tight side tension being 400 lb and
the minimum tight side tension is expected to be 160 lb, at a pulley diameter of 12 inches. For a
Goodman factor of safety of 1.8, recommend the diameter of the shaft. Consider a machined surface
and the effect of a hardened profile keyway in the shaft.
