Hi, I need help in these topics:
I have an exam this week.
-Fatigue Failure Resulting from Variable Loading
-Introduction to fatigue, fatigue life methods, stress life and strain life methods
-Endurance limit and fatigue strength
-Endurance limit modifying factors, stress concentration and notch sensitivity
-Fluctuating stresses and fatigue failure criteria for fluctuating stresses
-Torsional fatigue strength, combination of loading models, and surface fatigue strength
Shafts and Shaft Components:
-Shaft materials, shaft layout, and shaft stresses, deflection considerations and critical speeds for shafts.
-Miscellaneous shaft components: screws, keys and pins;
-limits and fits, stress and torque capacity in interference fits.
Attached is just an example of what I am seeking help in.
