1. (‘JJ) uses a certain machine to produce carjacks. The machine cost the company $90,000 three years ago. The reduced ...

s ago. The reduced book value now stands at $60,000. A new model of the machine is currently available for $139,350. The new machine has a useful life of five years, at which time it will be sold for $20,000. Using the new machine, the expected unit sales of the car jacks would be 6,000 car jacks per annum. The estimated unit selling price is $35 for the first year. As a result of the COVID-19 pandemic in Singapore, JJ is experiencing labour shortage. JJ will have to transfer workers from another department to the new project. These workers earn a contribution of $2 per direct labour hour in their original department. The fixed overhead cost would be $2.20 per hour and this is expected to remain unchanged. JJ’s products are being sold to a distributor. The sales agreement allows the selling price to rise at the rate of 10 percent per year after the first year. The unit cost price, except for fixed costs, is expected to increase at the same rate as the selling price. Working capital requirements are expected to be $15,000 in the first and second years, increasing to $18,000 in the third year and is expected to remain at this level till the end of the project. All the amounts of working capital will be recovered at the time of project termination. The new project uses cutting-edge technology and so enjoys a tax holiday from the authorities. The drawback of using this high-risk approach is that the new project requires a minimum return of 27 percent per annum. Required: Identify the relevant cash flows for the decision as to whether JJ should proceed to purchase the new machine. Note: To show all workings with accompanying explanations. Word count requirement: 800

2. Here is a scenario where you would have to deal with a customer who is being rude and abusive. You ...

work for as a customer service representative at a call center for a company that makes exercise equipment. A customer calls in complaining that her treadmill motor is smoking. She has called in previously and was informed that her warranty has been voided because she did not follow the maintenance instructions in the handbook for her machine. She is upset because no one ever told her about maintenance when she bought the machine. She starts calling you a crook for robbing her, and continues to call you names (including some we can’t print).  Explore what steps you would take in this situation to remain calm and relaxed.  How would you go about de-escalating the situation?  How do you avoid correcting the customer and putting her on the defensive?  If it became absolutely necessary, how would you phrase a warning to refrain from personal attacks?

5.J-Unit testing assignment in eclipse. The J-Unit test class is already given, the classes and interfaces have to be derived ...

rfaces have to be derived from it. And it also involves creating methods in those derived classes. And then running the J-Unit test to see if it will pass all the cases giving you green bar. We are also required create some J-Unit cases of our own. More Info attached in the PDF document only 5 pages worth of info. And the source file with the J-Unit class and Model package where all the classes should be added are attached.

7.Write a Slicer One of the key steps in processing an STL file for printing is slicing. STL files were written ...

s were written to make slicing a low memory task by storing each triangle at a single place. We already have code to do the following: A Generator that returns a triangle one at a time from an STL file (specifically an ASCII STL file). It Return the triangle as a list of 3D points (tuples), ignoring the normal. (from HW4) A function that takes a list of line segments, each line segment is a list of 2D points (tuples) and returns a single list of 2D points where the start of one segment is the end of another. ( from HW 3) A function that converts a list of 2D points to G-Code (lab 2) A function that writes GCode to a file To make a slicer you need to: Write a function that calculates the intersection of a triangle with a horizontal plane. The input of the function should be a list of 3D points (tuples). It should return a list of 3D points. See this website for hints on the mathematics (Links to an external site.) ( (Links to an external site.) ) Next you need to combine all of these different functions into a single workflow that takes in an STL file, a slicing height, print temperatures, movement speed , and extrusion speed and returns a G-code String which prints the walls of the STL file. It should have an outer iteration over slice heights of the STL, for each slice height, it should scan all triangles and make a list of the line segments that intersect the plane at that Z height. Then it should order those segments into a list of points. That list of points is then converted into gcode movement and extrusion commands. The entire system combines these slices with setup and shutdown Gcode for the ender 3 printer to make the print job. You may write to a file a layer at a time or at the end. Once the slicer is done: Run the previous function with a vase file such as one of the following files: Submit your code as a Jupiter notebook with the .gcode in it and, and an image of your print.
