Duluth, Minn. (NNCNOW.com) -- Civil Engineering students at the University of Minnesota Duluth conducted stress tests on concrete beams for their class today.
Students tested two 16 foot long concrete beams made up of different compositions.
They tested the beams to see how much pressure they could take before they cracked.
Neither of the beams broke during the testing.
Stress testing is important to ensure breakage to buildings and bridges doesn't happen.
"We tested two beams and saw how they behaved and we were expecting that the pre–stress concrete beam would be able to handle a heaver load and it did," said Denis Mikulic a senior engineering student at UMD.
UMD is one of the few civil engeneering programs in the country to conduct stress testing on beams.
