6/13 Analysis, calculations and results​

What is the main objective for learners by the end of the session in the T Level Technical Qualification in Engineering and Manufacturing?

• Understand how to conduct material testing

• Understand how material testing results are interpreted

• Learn the history of material testing

• Develop new material testing methods

What is the act of applying a force to a material known as?

• Loading

• Compression

• Tension

• Bending

Which of the following is NOT a form of loading?

• Compression

• Expansion

• Torsion

• Shear

What does Young's modulus measure in a material?

• The ability to conduct electricity

• The ability to withstand changes in length under tension or compression

• The ability to resist chemical reactions

• The ability to absorb heat

How is Young's modulus calculated?

• Strain divided by stress

• Stress divided by strain

• Force divided by area

• Length divided by width

What is Young's modulus a specific form of?

• Hooke's law of elasticity

• Newton's first law

• Pascal's principle

• Bernoulli's equation

How many times greater is the Young's modulus for steel compared to aluminum?

• Three times greater

• Twice as great

• Four times greater

• Equal

How does a change in cross-sectional area affect stress?

• A smaller area results in larger stress

• A larger area results in larger stress

• Area does not affect stress

• Stress is only affected by force, not area

What equipment is used to perform a tensile test for plotting a stress-strain curve?

• Hydraulic press

• Universal testing machine

• Oscilloscope

• Micrometer

What is the point called where a material transitions from elastic to plastic behavior on a stress-strain curve?

• Proportional limit

• Fracture point

• Yield point

• Ultimate tensile strength
