Understanding Solid Deformation

What is deformation caused by?

• Temperature changes in the environment.

• Natural aging of the material.

• Chemical reactions within the material.

• Stress or force applied to a material.

What does strain measure in solids?

• Strain measures the temperature of solids.

• Strain measures the weight of solids.

• Strain measures the deformation in solids.

• Strain measures the color change in solids.

What is the elastic modulus?

• The elastic modulus is the amount of energy a material can absorb before breaking.

• The elastic modulus is the temperature at which a material melts.

• The elastic modulus is a measure of a material's stiffness, defined as the ratio of stress to strain.

• The elastic modulus is the measure of a material's density.

What happens at the elastic limit?

• The material returns to its original shape.

• The material breaks completely.

• The material becomes stronger.

• The material begins to deform permanently.

What is ultimate strength?

• Ultimate strength is the stress at which a material begins to deform elastically.

• Ultimate strength refers to the weight of a material.

• Ultimate strength is the maximum stress a material can endure before failure.

• Ultimate strength is the minimum stress a material can endure.

What is the breaking point on a graph?

• A point where the graph changes behavior or characteristics.

• A point where the graph is completely flat.

• A point where the graph reaches its maximum value.

• A point that indicates the start of the graph.

How do you calculate Young's Modulus?

• Y = (F * L0) / (A * ΔL)

• Y = (F * A) / (L0 * ΔL)

• Y= (A * ΔL) / (F * L0)

• Y = (F * ΔL) / (A * L0)

What is Shear Modulus used for?

• Shear Modulus is used to measure a material's rigidity and its response to shear stress.

• Shear Modulus is used to determine a material's density.

• Shear Modulus measures a material's thermal conductivity.

• Shear Modulus indicates a material's electrical resistance.

What does Bulk Modulus measure?

• Bulk Modulus measures a material's resistance to compression.

• Bulk Modulus measures a material's density.

• Bulk Modulus measures a material's tensile strength.

• Bulk Modulus measures a material's thermal conductivity.

What is tensile strength?

• Tensile strength refers to the weight of a material.

• Tensile strength is the maximum amount of tensile (stretching) stress a material can withstand before failure.

• Tensile strength is the ability of a material to conduct electricity.

• Tensile strength is the measure of a material's thermal expansion.
