Hi all,
I have a hollow shaft of 2" outside dia to 1.25" inside dia, about 1.5 ft in length.I also have a notch going around the outside periphery of the shaft. The shaft also has 2 holes drilled tranversely through the shaft
The shaft will be rotating and will have torsion and probably bending load. I already calculated that the strength of this hollow shaft will reduce by about 15% compared to a solid 2" shaft.How can I further calculate the reduction in strength taking into consideration the drilled tranverse holes & the notch.Thanks in advance.

john
