The data from the three-point bending test can be use to determine the elastic modulus of the material.

Compressive stresses increase 

The general bending equation considers:

Under regular bending (load acting downward), the bottom of the beam is:

Find the cardinal number n(A) for the set. A = {2, 4, 6, 8}

The load in a bending test is applied through

The location of the displacement measurement depends on

For a beam with a rectangular cross section, the tensile zone is equal in size to the compression zone.

The report for the bending experiments should include 

1. Which microorganism is shown? [identify] 2. What are the larger pale circles shown in which the microbe is found? [circles]
