O Construct the B.E.P chart on a graph sheet and indicate, B.E.P, M.o.S and also indicate the new B.E.P & M.o.S after the improvement measures has been taken (With different colours). Show the calculations for the following parameters separately before and after the measures taken.1. Determine the B.E.P2. Determine the profit 3. Margin of safety.Also write your decisions taken to improve the profits of the company and to reduce the B.E.P.

An electric motor's torque is a function of the speed at which it rotates. Many brushed AC motors have a linear toque curve as shown below. If the power output of the motor is equal to the torque (T) multiplied by the rotational speed in rad/s (w), what is the maximum power you can get out of the motor if the stall torque (Tstall) is 0.001 Nm and the no load speed (wno load) of 14,332 RPM? Give your answer in Watts. There are two ways to solve this: Use a stall torque and no load speed and plot the torque profile below and then plot the power versus rotational speed to find the maximum. The second method is to determine the mathematical relationship for power given the information at the start of the question and set the differential of power with respect to RPM equal to zero, and solve for the RPM to get the maximum. Tstall Wno load W

For the following hydraulic circuit, we want to move a load of 2512 lb at a speed of 250 in/min. The cylinder has a diameter of 4 inches and a stroke of 20 inches. a) Calculate the speed (time)and the volume of the accumulator. b) Calculate the power forcharge the battery. c) The charging time ofthe accumulator

A robot is used for loading and unloading of parts to automated flexible machines. Loading time is 1 minute; unloading time is 1.5 minutes; machining time 15 minutes; Robot travel time between the machines including the inspection time is 3 minutes. Cost of robot C,=30 TL/Hour; cost of machines C2=40 TL/Hour. How many machines (integer number) should be assigned to the robot so that the total robot and machine costs per cycle are minimized? 8 - 176 a) 4 b) 3 c) 2 d) e) 6.

EXERCISES 3.1 A component experiences chance (CFR) failures with an MTTF of 1100 hr. Find the following: (a) The reliability for a 200-hr mission (b) The design life for a 0.90 reliability (c) The median time to failure (d) The reliability for a 200-hr mission if a second, redundant (and independent) component is added

The Union Manufacturing Company is producing two types of products: A and B. The demand forecasts, batch size, and time standards follow in table 2: Table No 2     Product A Product B Demand forecast (units/yr) 1,000 4,000 Batch size (units/batch) 20 10 Processing time (hr/unit) 3.2 4.5 Setup time (hr/batch) 10 20   Both products are produced on the same machine, called Mark I.                                                      i) What is the total number of hours required of Mark I equipment for the next year?  ii) The company works 250 days per year and operates two shifts, each covering 8 hours. If a 15 percent capacity cushion is maintained, how many hours of capacity can the company expect from each of its Mark I machines?

Determine the output pressure of a compressor operating with the following data: a. Actual power required to drive the compressor is 20 kW. b. Overall efficiency of the compressor is 75%. c. Compressor delivers four standard m3/min. d. Compressor inlet pressure is 100 kPa abs. Please use the equation in the picture to solve it.

Handwritten solution required. Strictly don't use chatgpt. If you use chatgpt ,I will report the answer for sure. Mechanical engineering dynamics.

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.

What is the availability (in %) of a system comprising the following components:a. Component Ai. MTBF = 100,000 hoursii. Repair time = 5 minutesb. Component Bi. MTBF = 1,000,000 hoursii. Repair time = 60 minutesc. Component Ci. MTBF = 150,000 hoursii. Repair time = 5 minutes
