Engineer Paper

Introduction This is an experiment to determine the mechanical properties by utilize pliant and cogency test. In this case we have to bash the atomic adhere and structure affect the mechanical holding of material. We strike to know contrasting crystal structure and antithetical coordination and different adhere type will affect the properties of material. We retain to the primary(prenominal) five properties of the material, toughness, Youngs modulus, yield specialism, ductility, and ultimate tensile strength. We need 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 split out relationship for for each one of material with their station and potential flat coat why those property croak to us. Such as stronger bonding type will precede high tensile strength and high yield strength. The disturbance will increase the ultimate stress of the material. Youngs modulu s 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 measurable the hardness by using Rockwell Hardness Test, master HRE. This gist a 1/8 inch diameter steel ball indenter with carbon kg load.We come out material on the HRE scale and twisted the wheel until the green button flashes. and s o form starts work and drilled the material! . When the machine stabilized and take the meet a stable add together after beep, we tape the number on the machine. We did this for each material three multiplication 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. thus we put material on the instron tech machine. First we manoeuvre the...If you hope to get a full essay, order it on our website: OrderCustomPaper.com
