Define Stress And Strain? |
|
Answer» Stress: The FORCE of resistance PER unit area, offered by a body against deformation is known as stress. Mathematically stress is written as F=P/A Where f= stress P=EXTERNAL force or load A=cross-sectional area. Unit of stress: stress is represented in N/m2 Strain: The ratio of change in dimension to the orginal dimension when subjected to an external load is termed as strain and is denoted by E. It has no unit. Stress: The force of resistance per unit area, offered by a body against deformation is known as stress.
