F TMC HIGITR BLLT TENSION

Design a shaft based on the loads and layout described above. The shaft should have an infinite life. You will decide how to attach each pulley to the shaft and design accordingly. The attachment components and dimensions should be based on tables in the textbook.

$-$ You need to consilier that the diameter of section $\backslash ($ A $\backslash )$ is $1\mathrm{.}2$ times the diameter of sections $\backslash ($ B $\backslash )$ and C $($designing a shaft with a constant diameter is not acceptable$).$ However, you may need to consider a constant diameter $($the smallest one$)$ during the calculations of deflection, slope, and critical speed.

$-$ Use the Goodman Line for fatigue criteria, with a minimum safety factor of $1\mathrm{.}25.$ Also, check for yield failure.

$-$ The shaft speed is $550$ RPM$.$ Calculate the critical speed of the shaft to confirm an adequate margin.

$-$ The slope and deflection must satisfy the criteria in Shigley Table $7-2.$

Submit the following:

$-$ Design calculations

$-$ A SolidWorks, AutoCAD, hand, or similar drawing that dimensions all pertinent shaft features.
