Snap, Crack, and Twist

Snap, Crack, and Twist

      The young women from YWPN discovered how different material properties can influence the strength of a material. This lab used 3 chocolate bars with different ingredients to demonstrate how various microstructures affect the flexural strength of the bars. This "strength" is measured by a 3-point bending test where pennies were added slowly to a cup to measure how much load or stress the material could handle before breaking.

      This lab used chocolate bars as an example of how glass can have different make-ups and microstructures depending on its intended use. The students learned why it is important for scientists and engineers to understand the mechanical properties of different materials before using them.
