Scientific Assistant 2 Interview Questions and Answers

Stress strain diagrams show the relationship between stress and strain in a material.

• Stress strain diagrams help in understanding the behavior of materials under different loading conditions.

• The slope of the stress strain curve represents the material's stiffness or Young's modulus.

• The area under the stress strain curve represents the material's toughness or energy absorption capacity.

• Different materials exhibit different stress strain behaviors, such as brittle, ductile, or ...read more

Manufacturing operations include casting, machining, welding, and assembly.

• Casting involves pouring molten metal into a mold to create a specific shape.

• Machining uses tools to remove material from a workpiece to achieve the desired shape.

• Welding joins two or more pieces of metal together using heat and pressure.

• Assembly involves putting together individual components to create a finished product.

The iron-carbon phase diagram shows the phases and phase transitions of iron and carbon alloys.

• The phase diagram shows the relationship between temperature, composition, and phases present in iron-carbon alloys.

• It consists of regions representing different phases such as austenite, ferrite, cementite, and pearlite.

• The eutectic point on the diagram represents the composition at which the alloy transforms from liquid to solid.

• The phase diagram is crucial for understanding the p...read more
