Engineer Paper

Introduction This is an experiment to determine the mechanical properties by utilise pliant and insensibility test. In this case we have to hunch the atomic adhere and structure affect the mechanical seat of material. We strike to know contrasting crystal structure and polar coordination and different hold fast type will affect the properties of material. We calculate to the primary(prenominal) five properties of the material, toughness, Youngs modulus, yield specialism, ductility, and ultimate ductile strength. We bring 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 reserve out relationship for for each one of material with their proportion and potential flat coat why those property derive to us. Such as stronger bonding type will declaration high tensile strength and high yield strength. The dislocation will increase the ultimate stress of the material. Youngs 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 c lock away 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, master HRE. This gist a 1/8 inch diameter steel ball indenter with one hundred kg load.We come out material on the HRE scale and twisted the wheel until the green bu tton flashes. and so car starts work and d! rilled the material. When the machine stabilized and take the support a stable add together after beep, we leger the number on the machine. We did this for each material three clock 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. wherefore 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
