Compare and contrast tensile stress, compressive stress, and shear stress
What will be an ideal response?
Tensile stress results from forces pulling outward at opposite ends of a material, stretching the material.
compressive stress is the exact opposite of tensile stress. Instead of being stretched, the material is compressed: the forces act inwardly on the object.
An object under shear stress has equal and opposite forces applied parallel to its opposite faces.
