Lab report on stress concentrations Essay Example

Lab report on stress concentrations Paper In order to find the stress in that direction, we need to know the strain in that direction, and use Hookers Law to find the stress. 7. We did not use gages 7 8, so the data required for this calculation is not available. CONCLUSIONS This lab has given us a better understanding of how stresses are dispersed amongst a rod with indentations and impurities such as holes. Due to our calculations we noticed that at the points directly attached to the tangent surfaces of the hole, the sensors calculated to the most stress. Also, our stress averages of 2. 025 and 2. 0126 were very comparable to the given graphical values of 2. 1. Some of the errors in the lab could have been to the machine error, or simply human error. Perhaps the sensors were not placed in the correct spots, and maybe the correct number of significant figures was not used or carried throughout the lab. We enjoyed conducting this lab and hope to see more stress train labs in the future. ASSESSMENT If this lab was conducted a second time, some suggestions are as follows. It would have been nice to have a more hands on experience with the lab. It would have been nice to have individual concrete samples so each of us could see the data being calculated and so we could understand where certain values were coming from. It would be interesting to then tensile stress test the samples that we prepared as a team the following week. We understand that there are also questions that must be reviewed in class, but it would be nice to have done 60% lab, 40% discussion.
