Question

What type of stress are you applying when you press on the ends of a wooden rod? When you pull on its ends?

a) Tensile stress; Compressive stress
b) Compressive stress; Tensile stress
c) Shear stress; Tensile stress
d) Tensile stress; Shear stress

Answer 1

Pressing the ends of a wooden rod applies compressive stress, while pulling on its ends applies tensile stress. Both types of stress refer to the object's deformation due to the applied forces.

The Correct option is; a) Tensile stress; Compressive stress

Step-by-step explanation:

When you press on the ends of a wooden rod, you are applying a compressive stress; when you pull on its ends, you are applying a tensile stress.

This categorization of stress refers to the forces acting on the rod and how they deform it. Tensile stress occurs when forces are applied in such a way that they stretch the object, causing its elongation. In contrast, compressive stress happens when forces are applied that squeeze the object, causing it to compress or shorten.

Yes, a rubber band can experience compressive stress if it's squashed rather than stretched.
