03-08-2021· ER Diagram stands for Entity Relationship Diagram, also known as ERD is a diagram that displays the relationship of entity sets stored in a database. In other words, ER diagrams help to explain the logical structure of databases. ER diagrams are created based on three basic concepts: entities, attributes and relationships.

E (Steel) ≈ 30 x 106 psi E (Aluminum) ≈ 10 x 106 psi E t ⇒ Tangent Modulus - Slope of the stress-strain curve above the proportional limit. There is no single value for the tangent modulus; it varies with strain. G ⇒ Shear Modulus - Slope of the initial linear portion of the shear stress-strain diagram. G (Steel…
Stress-Life Diagram (S-N Diagram) The basis of the Stress-Life method is the Wohler S-N diagram, shown schematically for two materials in Figure 1. The S-N diagram plots nominal stress amplitude S versus cycles to failure N. There are numerous testing procedures to generate the required data for a proper S-N diagram.

a. The E-R diagram is shown in Figure 7.2. Note that an alterantive is to model examinations as weak entities related to a section, rather than as a strong entity. The marks relationship would then be a binary relationship between student and exam, without directly involving section. b. The E-R diagram …
