Stress Diagram Science. Stress strain diagram for brittle material. Four types of stresses act on materials.
Stress external deforming force f area a its si unit is nm 2 or n m 2. Since the rock cannot move it cannot deform. This is called confining stress.
Since the rock cannot move it cannot deform.
Stress is the force applied to an object. A resilience test b rotating beam test c ductility test d tensile test 2. Elastic limit is the limiting value of stress up to which the material is perfectly elastic. The stress strain diagram provides a graphical measurement of strength and elasticity of the material.
