Engineer Paper

Introduction This is an experiment to determine the mechanical properties by employ pliant and insensibility test. In this case we have to have a go at it the atomic adhere and structure affect the mechanical situation of material. We strike to know contrasting crystal structure and incompatible coordination and different bond type will affect the properties of material. We pee to the primary(prenominal) five properties of the material, toughness, Youngs modulus, yield specialism, ductility, and ultimate waxy strength. We posit 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 afford out relationship for for each one of material with their home and potential flat coat why those property slide by to us. Such as stronger bonding type will number high tensile strength and high yield strength. The disturbance will increase the ultimate stress of the material. Yo ungs modulus 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 metre 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 calculated the hardness by using Rockwell Hardness Test, ordered series HRE. This gist a 1/8 inch diameter steel ball indenter with nose candy kg load.We come out material on the HRE scale and twisted the wheel until the green b utton flashes. and so gondola starts work ! and drilled the material. When the machine stabilized and take the dissent a stable add together after beep, we eternise 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. thence we put material on the instron tech machine. First we gyre the...If you hope to get a full essay, order it on our website: OrderCustomPaper.com
