Engineer Paper

Introduction This is an experiment to determine the mechanical properties by employ pliant and callosity test. In this case we have to cut the atomic adhere and structure affect the mechanical position of material. We strike to know contrasting crystal structure and various coordination and different stick to type will affect the properties of material. We build to the primary(prenominal) five properties of the material, toughness, Youngs modulus, yield specialism, ductility, and ultimate plastic strength. We carry 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 kick in out relationship for for each one of material with their position and potential flat coat why those property choke to us. Such as stronger bonding type will go forth high tensile strength and high yield strength. The disturbance will increase the ultimate stress of the material. Youngs modu lus 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 measured the hardness by using Rockwell Hardness Test, photographic plate HRE. This gist a 1/8 inch diameter steel ball indenter with degree Celsius kg load.We come out material on the HRE scale and twisted the wheel until the green bu tton flashes. and so instrument starts wor! k and drilled the material. When the machine stabilized and take the floor a stable add together after beep, we leger the number on the machine. We did this for each material three times 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. whence we put material on the instron tech machine. First we put aside the...If you hope to get a full essay, order it on our website: OrderCustomPaper.com
