DesignTech Systems Junior Engineer Interview Questions and Answers

Theories of failure explain how and why materials fail under different conditions.

• Theories of failure are used to predict the failure of materials under different loads and conditions.

• There are different types of theories of failure, including maximum shear stress theory, maximum normal stress theory, and maximum strain energy theory.

• Maximum shear stress theory states that failure occurs when the maximum shear stress i...read more

Basic material properties include density, strength, hardness, elasticity, and conductivity.

• Density refers to the mass per unit volume of a material.

• Strength is the ability of a material to withstand external forces without breaking or deforming.

• Hardness is the resistance of a material to indentation or scratching.

• Elasticity is the ability of a material to return to its original shape after being deformed.

• Conductivity ...read more
