  12. STRESS!!! tension, strain, and compression • Stress – the force applied per unit of area • Strain - is perpendicular to that of the force applied to an object, and defines how much an object is deformed compared to its original status • Tension – Acts to lengthen an object • Compression – Acts to shorten an object
