1. Define Hooke's Law.
Ans. It establishes that when the material is loaded within the elastic limit, the stress is directly proportional to the tension. that is,
voltage tension. or stress = constant x tension
2. Define the strength of the materials.
Ans. The strength of a material is its ability to withstand applied stress without failure.
3. What is stress?
Ans. When a load is applied to any object, a resistance force, resistance or reacting by unit cross-sectional area is called stress.
4. What is tension?
Ans. Stress is change in dimensions over the original dimensions.
5. What is deformation?
Ans. The deformation is the change in the dimensions of any object due to the applied load.
6. In what steel has the stress test been performed. What is its carbon content?
Ans. In mild steel (0.3 to 0.6% carbon).
7. What type of fracture has occurred in the extensible specimen?
Ans. Ductile fracture
8. Define the temperature stress.
Ans. Stress introduced by uniform or non-uniform temperature change in a structure or material which is limited against expansion or contraction.
9. What is hardness?
Ans. Hardness is the resistance of a material to localized deformation.
