Stress, Strain and Young Modulus Crossword Puzzle

QUESTIONS LIST:

• stress : the force per unit area applied to a material.
• strain : the extension per unit length of a material under stress.
• young modulus : the ratio of stress to strain in the linear region of deformation.
• elastic : a material that returns to its original shape after deformation.
• plastic : a material that does not return to its original shape after deformation.
• hookes law : the law stating that force is proportional to extension for small deformations.
• elastic limit : the maximum stress a material can withstand before permanent deformation.
• yield point : the point beyond which a material undergoes large extension with little force increase.
• work done : the area under a force-extension graph.
• elastic deformation : type of deformation where a material returns to its original shape after force removal.
• plastic deformation : type of deformation where a material is permanently stretched.
• linear region : the region in a force-extension graph where hooke’s law is obeyed.
