Two forces, 100 kN and 200 kN, act on the rectangular column in the figure. Find the stresses at A and B points according to the given and show them on the stress element.

The properties of materials can be classified into the following categories: Mechanical Physical Thermal Electrical Magnetic Describe each category, include two specific properties in the description and say why those properties are of interest to a design engineer.

engineering stress, o CO b) Offset (x) 1. Which material has the highest yield strength? 2. Which material has the highest ultimate tensile strength? 3. Which material has the lowest tensile modulus (aka Young's modulus)? 4. Which material has the highest toughness? c) engineering strain, & 5. What offset (x) in engineering strain () should be used to calculate the yield strength? a. 2 b. 0.2 c. 0.02 d. 0.002 e. 0.0002

When can a theory of failure be used as a basis for design?
