put alpha = 9 In this question you are required to consider the deflection and vibration of a simple cantilever beam (Figure3a), based on an experimental scenario that you can create at home or in the labs at Deakin. All dimensionsand materials are to be chosen by you. However, a 40cm plastic ruler or longer metal or wooden ruler may bea good scenario to examine.1)Figure 3: Schematic of cantilever beam for Question 3.Your task is to answer the questions shown in Table 5, using the calculation methods specified.Hint: for Part (a) of this question, you can use the following beam deflection equation to calculate the modulusof elasticity, based on a number of applied loads.PL38 =3EITable 5: Calculations and explanation required for Question 3.1. Experimental- 2. Simple handbased3. Finite elementcalculations basedon assumed material Abaqus CAEcalculations usingmeasurementsproperties andgeometry(1 mark)(3 marks)(3 marks)a) Determine Young's modulus of thematerial, based on measurement of theassumedeflection at a number of end loads.b) Determine the first natural frequency. Forexperimental measurement you can use video,accelerometer, position sensor, stopwatch andmanual counting, etc.c) Attach a small weight to the end (point 2)and determine the first natural frequencyagain. The weight should be small so that itdoes not alter the shape of the beam too muchprior to oscillation.d) Comment on whether the results arereasonable, where there may be sources oferror (based on the assumptions /simplifications of each method), how theresults of each of the methods compare andwhy there may be discrepancy between themethods. A single table summarising theresults from both methods may be helpful forthis.1. Experimental- 2. Simple handbased3.
