In the design of a shaft, the presence of keyways, holes, or other notches can introduce stress concentrations. What is the typical method to compensate for these stress concentrations?
1
Applying a surface treatment to the notched region
2
Introducing fillets at the root of notches
3
Using materials with higher elasticity
4
Increasing the shaft diameter proportionally to the notch depth
