Sorry, should have specified more: The axle in question is the spindle of a bicycle, with the two crank arms attached to it. The two crank arms each have bike pedals of negligible mass that receive loads from the rider. So yes on the loads on the crank shafts. There is also a gear on the axle...

I will be doing fatigue analysis, so I figured that wasn't the same, thanks. From what I looked up for mass MOI (3rd Figure): http://hyperphysics.phy-astr.gsu.edu/hbase/mi.html I have a few questions: For the horizontal axle and two cranks that basically looks like this (ignore the a's)...

Homework Statement Not really a HW problem (no diagram), I just need to figure out this number for a design. I have an axle with two crank arms attached to either end, pointing in opposite directions. The entire thing will spin. I need to find the equivalent moment of inertia of the axle...
