What load are spring hooks subjected to?
- Bending.
- Tension.
- Compressive.
Explanation
The hook formed at the end of a tension spring is a curved cantilever, so when the spring is pulled the hook is loaded in bending rather than in pure tension. This is why hooks are a common fatigue-failure point and are inspected carefully.

Can anyone explain to me why the answer is bending not the tension?

Imagine soft metal ring with 1 cut, like this: http://www.doomlegends.com/maille/wire_cutters.jpg
You are holding it in two opposite positions and trying to tension it. What will happen with ring?

Correct answer is b. https://images.app.goo.gl/XbaWnydchXsTwMob6. Its a spring hook not a single coil spring.

A spring hook basically is being pulled so the correct should be tension.
