Question
The beam below is subjected to a sinusoidal forcing function with Fmax = F and Fmin
-F/2 where l
40 mm. The cross section is a rectangular with thickness (t) and height (h). The beam is
in room temperature, it is ground, it is 90% reliable. Find the stress state in the beam due
to this loading. choose the type of steel that will give a safety factor of 3 for N=5E8
cycles using Goodman.
