1.4. Types of Stress

Try these first

1. 1.

   Define tensile stress.

   Hint

   Think about stretching a rubber band.

2. 2.

   What is compressive stress?

   Hint

   Consider when you press down on a sponge.

3. 3.

   What type of stress is related to pulling forces?

   • Tensile Stress
   • Compressive Stress
   • Shear Stress

   Hint

   Think of stretching a rubber band.

4. 4.

   True or False: Compressive stress can lead to material shortening.

   • True
   • False

   Hint

   Consider the effect of pressure on a sponge.

5. 5.

   If a rod experiences a tensile stress of 4000 N/m² and the cross-sectional area is 0.05 m², what is the total force applied to the rod?

   Hint

   Rearrange the formula for tensile stress to solve for force.

6. 6.

   Illustrate how shear stress would affect a material if subjected to a twisting motion. Provide an example.

   Hint
