Material Properties PLTW Part 1

What is the formula for calculating density?

• Density = volume / mass

• Density = mass / volume

• Density = mass x volume

• Density = mass + volume

• The stiffness of a material

• The melting point of a material

• The electrical conductivity of a material

Which property describes the maximum amount of pulling force a material can handle before it breaks?

• Yield Strength

• Ultimate Tensile Strength

• Fracture Toughness

• Ductility

What is the term for the temperature at which a solid turns into a liquid?
