Internal Pressure - Lab Report ExampleWe will do this by graphing experimental results versus hypothetical calculations. We will take into account the error of the measuring system.We will also investigate the role gauge factor, Youngs Modulus, and Poissons ratio play in the effects on variant with pressure. Finally, we will project the outcome of the experiment on the cylinder as the pressure increases to some unknown large finite threshold.If one were to recall of this as in a cylindrical coordinate system, the longitudinal strain would be that acting in the Z direction whereas the cirucumferential (otherwise known as the discursive or lateral) strain would be acting in the direction of theta and not radially.both ends eliminating any longitudinal stress or strain. Our sheath consists of the second case of a thin cylinder with closed ends. In a thin cylinder with closed ends, longitudinal stresses and strains exist, and both circumferential and longitudinal strains depend on bo th stresses respectively.The use of a pass on pump allows one to make step measurements of strain at each increment of pressure provided by the hand pump. Each step measurement has a corresponding data point in the table of results.A bourdon gauge is used because it has a subway you can insert inside the cylinder that has the capacity to expand with increasing pressure. The gauge measures the change in its own resistance delta R, and this delta R measured is instantaneously proportional to the respective strain as well as the original resistance R. The gauge factor is a constant of proportionality between the strain and R, and delta R. The gauge factor of 2.06 is a very typical value for gauge factors. Annealed aluminium is a somewhat ductile or soft metal. Using annealed aluminium is responsible for a somewhat low value of the Youngs modulus. The Youngs modulus of a substance is a measure of the stiffness of that material. The lower E is, the higher the strains will be. becaus e annealed aluminium results in larger strains making it easier to detect and record the measured strain.Once strain is determined its value can be
