Answer to Question 1

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.

Answer to Question 2

D
