The force applied and the diameter of the diameter of a hardened steel ball is kept constant while four different specimen blocks namely, aluminum, brass, copper and mild steel are penetrated by the indentation steel ball to create different indentations on each of them. The diameters of the indentions allow us to obtain the Brinell Hardness number to predict the hardest and the softest material among them. The experimental data would also allow us to compare the hardness measured with the other published results from other

    The team also noticed some inconsistencies in the graph that they feel could be fixed by changing their code. One of these issues being that cutting off power completely from the AEV’s resulted in the motors having to do extra work in order to get started again. Possibly changing the code so the amount of power supplied to the motors gradually decreased over time instead of stopping the power completely, could make for a more efficient AEV. Theoretically speaking, when a plane begins to near its destination the pilot begins to lower the amount of thrust given to the engines, not cease thrust completely, so if the team were able to find a way to mimic this, they feel that their AEV could save energy overall, and become more productive.…

Additional permissions to the bucket to enable endpoint access are necessary whenever using Amazon VPC endpoint for Amazon S3.…
