Strength of materials
https://en.wikipedia.org/wiki/Strength_of_materials

1. In general, the author of the article selects most of its content from a published text book. Therefore, the content is neutral and authentic. However, the article provides four failure theories and the microstructures of the materials in the last section without any citation. Without the reference, readers are unable to know whether the theories are credible or not. Furthermore, the author also mentions that some theories or method was first invented or related to some scientists. I believe that the references are also needed at those positions.

2. The article provides comprehensive knowledge of strength of materials. However, there are still two positions in the article that further information or explanations can be added. First, in the first paragraph, the author mentions one of the pioneers of the mechanics of materials: Timoshenko. Since the theory invented by Timoshenko is widely used to solve the problems in the field of materials mechanics, the content of the theory can be added after the first paragraph. Similarly, ‘Euler–Bernoulli beam theory’ is another theory that always presented with ‘Timoshenko theory’ because ‘Euler–Bernoulli beam theory’ can be used to solve problems easier but not as accurate as ‘Timoshenko theory’. Therefore, some explanations of ‘Euler–Bernoulli beam theory’ are needed. Moreover, the last paragraph involves the discussion of microstructures and metal hardening processes. There are some names which describe the microstructures such as martensite, bainite and austenite. It’s better to mention these names in order to form the relation between the microstructures and hardening process.
