...ME 303 MANUFACTURING ENGINEERING PROBLEM SETS Prepared by: Kamil Özden Ural Uluer Salih Alan Mehmet Bilal Atar PROBLEM SET FOR CHAPTER 2 Q2.1 A copper bar is to be cold rolled into a section which must have a min. tensile strength of 390 MPa. If the final cross-sectional area is 20.13 mm2 and assuming the flow properties of the workpiece material are given as K = 450 MPa, n = 0.33. Calculate the followings: a) The tensile strength of the annealed material. b) The initial diameter of the copper bar. Solution It is important to understand the question well. In this question, the copper bar is annealed first then a cold rolling operation is done on it. Initial diameter of the copper bar is same before and after the annealing operation. a) Flow stress of the plastically deformed bar could be shown as shown in Course Slides at UTS Then UTS of the original bar (no annealing, no cold working) is found as below: = 450 (0.33)0.33 = 312.12 MPa . As u u Since before necking occurs ( < n) area stays constant at the whole bar, the formula below could be used: By putting the area ratio into the formula (i) UTS of the annealed material is found as: b) For this question d0 can be found by using the ratio: if < n (which means necking is not started yet) with the UTScw value given in the question as UTScw = 390 MPa, to check the value So > n which means that necking started, then UTScw becomes equal to flow stress of the deformed material, Q2.2 A...

...Name: Thao Vo Title: The Optics of the Eye Section 202 Monday 4:30pm – 7:15pm Course Name: Physics 246 Lab Partner’s Name: Jennifer Darlington, Hyon Hodge Date: 11/12/2012 Instructor: Dr Vermuru Word Count: 1650 Aim: The aim of this experiment is to examine a scaled up model of the human eye to understand the image formed in the eye, the optics of accommodation, nearsightedness, and farsightedness. Introduction: The basic structure of the human eye consists of cornea, natural crystalline lens and retina, as shown in Figure 1, in which the lens of the eye does little of the bending of the light rays, most of the refraction is done at the front surface of the cornea and retina plays the role of the film in a camera. Figure 1: Diagram of a human eye Accommodation is the focusing adjustment in which the muscles in the eye change the shape of the crystalline lens to change its focal length. Figure 2: Accommodation by a normal eye a) Lens relaxed, focused at infinity b) Lens thickened, focused on a nearby object Nearsightedness refers to an eye that can focus only on nearby objects. Because the far point is not infinity but some shorter distance, distant objects are not seen clearly. This defect is usually caused by an eyeball that is too long and images of distance objects are focused in front of the retina. In order to correct this defect, a diverging lens should be used as it causes parallel rays to diverge which allowing the rays to be focused at the...

...1. a. What observations can you make about the overall shape of each graph? (Imagine that you are drawing a line that connects the tops of the horizontal bars.) The shapes of the distributions look like bell curves and also show normal distribution. b. What do the shapes of the two graphs indicate about the distribution of beak depth measurements in these two groups of medium ground finches? The shapes of the two graphs indicate that there is variability in the beak depth trait among the birds and that most birds have beak depth measurements that arrive right around the mean. 2. Compare the distribution of beak depths between survivors and nonsurvivors. In your answer, include the shape of the distributions, the range of the data, and the...

...Pattern Allowances The patterns are not made the exact size as the desired casting because such a pattern would produce undersize casting. When a pattern is prepared, certain allowances are given on the sizes specified in the drawing so that the finished and machined casting produced from the pattern will conform to the specified sizes. While designing pattern, the allowances commonly considered are discussed below. 1. Shrinkage Allowance Generally metals shrink in size during solidification and cooling in the mould. So casting becomes smaller than the pattern and the mould cavity. Therefore, to compensate for this, mould and the pattern should be made larger than the casting by the amount of shrinkage. The amount of compensation for shrinkage is called the shrinkage allowance. Generally shrinkage of casting varies not only with material but also with shape, thickness, casting temperature, mould temperature, and mould strength. Therefore, it is better to determine the amount of shrinkage according to the past record obtained from many experiences. Table 1.2 shows an average amount of shrinkage for important cast metals. Table 1.2 Typical shrinkage allowances for important casting metals Type of metal Amount of shrinkage (%) Grey cast irons 0.55-1.00 White cast irons 2.10 Malleable cast irons 1.00 Steels 2.00 Manganese steel 2.60 Magnesium 1.80 Type of metal Zinc Brasses Bronzes Aluminium Aluminium alloys Tin Amount of shrinkage (%) 2.60 1.30-1.55 1.05-2.10 1.65 1.30-1.60 2...

...MERIDIAN MANAGEMENT SCHOOL (MMS) Mini Case Study Analysis (Human resource Perspective) 1.0 EXECUTIVE SUMMARY The Management School of Meridian University is a specialist Postgraduate management school. MMS has being established 15 years before this case study was written since then MMS became leader in the field of postgraduate management. MMS has wide portfolio of courses both fulltime and part-time basis this was partly because of easy procedure for introducing new course. MMS has its own dedicated staff headed by head of school. The other staff of MMS composed of 20 academic staff, one SAO and 4 administrators from the four different divisions of MMS namely: Organisational Behaviour/Human Resource Management, Operation Management, Finance & Economics and Marketing. The organisational structure of MMS had relative flat structure, the academic staff who were equally divided into the four subject divisions were either lecturer or senior lecturer. In addition to that senior lecturer were only in a higher grade of the Salary scale of MMS but had same condition of employment with the lecturers. Currently MMS is facing problem of losing important staff who were important for the smooth going of school activities at a critical time of the year when MMS is getting ready for the new intake. 2.0 ISSUES: There a number of issues related to this case but I will concentrate more on issues on staffing since it is the most critical issue in this case.
