Engineer Paper

Introduction This is an experiment to determine the mechanical properties by employ pliant and asperity test. In this case we have to bonk the atomic adhere and structure affect the mechanical berth of material. We strike to know contrasting crystal structure and polar coordination and different hold fast type will affect the properties of material. We allot to the primary(prenominal) five properties of the material, toughness, Youngs modulus, yield specialism, ductility, and ultimate bendable strength. We call for to know the relationship between the properties of material. We also need to know how hardness relate to those properties. In this experiment, we will vow out relationship for for each one of material with their proportion and potential flat coat why those property arrive to us. Such as stronger bonding type will force high tensile strength and high yield strength. The equipment failure will increase the ultimate stress of the material. Youngs mo dulus are metric the harshness of the material that relate to the bonding of the material. Ductility indicates the ability to tractile deformed. Procedure After the introduction, it is measure to start experiment now. There were cardinal different materials in front of us.

They are brand, brass, copper, aluminum, polycarbonate, polyethylene, and polystyrene First part, we thrifty the hardness by using Rockwell Hardness Test, collection plate HRE. This gist a 1/8 inch diameter steel ball indenter with degree centigrade kg load.We come out material on the HRE scale and twisted the wheel until the green button flashes. and so implement starts wo! rk and drilled the material. When the machine stabilized and take the survive a stable add together after beep, we translate the number on the machine. We did this for each material three c hire and on different surface, and then we calculate the average hardness for each material that we test on. Second part we measured the width, thickness, and bore length of the material by use calipers. indeed we put material on the instron tech machine. First we lock the...If you hope to get a full essay, order it on our website: OrderCustomPaper.com
