QUESTIONS AND ANSWERS.
1. Compressive strength - correct answer - the force at which a material
breaks under pressure
2. Tensile strength - correct answer - a measure of how much stress from
pulling, or tension, a material can withstand before breaking.
3. Bending strength - correct answer - the ability to resist forces that may
bend the material.
4. Shear strength - correct answer - measures the largest shear force a
materials can stand before ripping apart
5. Torsional strength - correct answer - resists a twisting force
