A CNC milling machine has a purchase price of £100,000 and it is considered from an accountingstandpoint to be depreciated to zero value over a period of 6 years. If the machine is to be used for 2shifts with each shift working for 37 hours/week and 45 weeks/ year. What is the machine cost/ hr whichmust be charged in order to amortise the costs over the 6 year period? Express your answer in £/ hourbut just write the numerical answer rounded up to the nearest penny.To make the calculation simpler ignore the effects of compound interest, you can assume that over the 6year period you will be required to pay back borrowed money for the machine purchase amounting to 6%interest on the sum borrowed.

Here's a detailed calculation for better understanding. The total number of working hours over the 6…

It takes an operator 2 min to service a machine and 0.5 min to walk to the next machine. Each machine runs automatically for 3 min, the operator earns $12/h and the machine costs $25/h to run. What is the total expected cost per unit of production if 2 machines are assigned to the operator? $37 $77.5 $1.29 $62 $1.03
The initial cost of a machine for a production facility is $225,000. The machine is expected tolast for 10 years with no salvage value. The company’s tax rate is 49% and SLD is used todepreciate the machine. For this type of depreciation, the tax life of the machine is considered 8years and its salvage value is $5,000. The after-tax rate of return is 14.3%. Determine the uniformannual before-tax cash flow.
1.) A.) A cutting operation is performed on a piece of metal. The rake angle of the tool, α, is eight degrees. The tool penetrates the work to a depth of 8mm. The chips generated from this cut are 20mm thick. Calculate the shear plane angle, Φ, in the orthogonal model for this operation. Give your answer in degrees B.) For the same cutting operation, the cutting and thrust forces are measured. The cutting force is measured as 1600N, and the thrust force is measured as 1300N. The width of the cut is 4mm. What is the shear stress applied by the tool? Give your answer in MPa.
The M–N plant manufactures two different products: M and N. Selling prices and weeklymarket demands are shown in the following diagram. Each product uses raw materialswith costs as shown. The plant has three different machines: A, B, and C. Each performsdifferent tasks and can work on only one unit of material at a time.Process times for each task are shown in the diagram. Each machine is available2,400 minutes per week. There are no “Murphys” (major opportunities for the system tofoul up). Setup and transfer times are zero. Demand is constant.Operating expenses (including labor) total a constant $12,000 per week. Raw materialsare not included in weekly operating expenses.a. Where is the constraint in this plant?b. What product mix provides the highest proi t?c. What is the maximum weekly proi t this plant can earn?
The amount of bell wire in inventory is to be approximated by weight. The weight of the wire is listed in the catalog as 2 1/4 ounces per 100 feet. An empty spool of the roll weighs 1 1/4 ounces. If the roll to be inventoried weighs 20 3/8 ounces, what is the approximate amount of wire on the spool in feet?
Q5) Assume that 2 automatic machines have been assigned to one operator. It takes 2 minute to load a machine, 2 minute to unload a machine, 5 minutes of automatic machine time, and 2 minute to inspect and pack a finished part. Draw machine operator chart and determine the amount of idleness that happens to either operator or machines as well as cycle time.
True, False or Uncertain. Explain your answer. Own wage elasticity JELLlincrease if product demand elasticity n? is high. In short run, when there is an increase in wage rate, each firm will hire less labor and so the industry labor demand is simply the horizontal summation of firm's labor demand. а. b. Labor demand is represented by the marginal revenue produce schedule (MRP) when we have competitive product market while it will be represented by the value of marginal product schedule (VMP) when we have a product market monopolist. When elasticity of substitution, SLK, increase that means the L and K are less substitutable, and the isoquant will be L-shaped. Minimum wage imposed by the government is always bad for the economy because it increase unemployment and deadweight loss. с. d. e. 3.

A toy factory is planning to make an additional item, which would be processed in 4 departments. The company is proposing to produce 600,000 units per year, working 250 days per year. The estimates of times made by an industrial engineer are in the table: Departments Times 1 2 3 4 Average processing time (second/part) 8 13 10 50 Average maintenance, time/day (minutes) 20 30 20 15 Average daily setup, time (minutes) 20 15 30 20 Average bookkeeping, time/day (minutes) 10 8 12 5 Machine adjustment, time/day (minutes) 15 10 15 15 Defective items, (% of production) 5 6 4 4 The parts are produced within the departments in a sequential manner (from department 1 to 2 to 3 to 4). Determine the efficiency of each departmental operation if only one shift is operated between 7:30 am-4:30 pm, with a 40 minute lunchbreak and two 10 minute coffee breaks.
