Which of the following is NOT a primary type of mechanical test performed using a Universal Testing Machine (UTM)?

• Tension
• Compression
• Torsion
• Bending

In a tensile test, the point at which the material begins to deform plastically is known as the:

• Ultimate strength
• Yield strength
• Fracture strength
• Elastic limit

A ductile material exhibits which of the following characteristics during a tensile test?

• Brittle fracture
• Significant plastic deformation before failure
• High modulus of elasticity
• Low yield strength

The modulus of elasticity (Young's modulus) is a measure of a material's:

• Strength
• Stiffness
• Ductility
• Toughness

Which of the following tests is used to determine a material's resistance to shearing forces?

• Tensile test
• Compression test
• Shear test
• Bending test

In a bending test, the maximum deflection of a beam is a measure of its:

• Stiffness
• Strength
• Ductility
• Toughness

The strain rate in a tensile test can affect the material's:

• Modulus of elasticity
• Yield strength
• Ultimate strength
• All of the above
