12.1. Tensile Testing

Try these first

1. 1.

   What is the purpose of tensile testing?

   Hint

   Think about what happens when you pull something.

2. 2.

   Define yield strength.

   Hint

   It's the beginning of plastic deformation.

3. 3.

   What does tensile testing primarily measure?

   • Corrosion resistance
   • Mechanical properties
   • Thermal conductivity

   Hint

   Think about what happens during pulling.

4. 4.

   True or False: Yield strength is when a material permanently deforms.

   • True
   • False

   Hint

   Recall the concept of bending without returning to shape.

5. 5.

   Calculate the safety factor for a beam if the yield strength is 250 MPa, and the anticipated load results in a maximum stress of 80 MPa.

   Hint

   Safety factors are about ensuring materials can endure greater stress than what they will actually encounter.

6. 6.

   A tensile testing sample has a UTS of 310 MPa and an elongation of 15%. Determine if this material is suitable for use in high-durability structures.

   Hint

   Consider applications that require both strength and flexibility.
