To calculate BMEP (Break mean effective pressure), what factors do i need to know?

How does the Holding Pressure reduce the material shrinkage in Injection Molding process? Explain this in terms of the internal structure of material

6) What are some effective ways of controlling mold temperature and mold build up?

When developing prototype tooling, discuss some of the techniques used in the evolution of injection molds.

8) Why is trying to maintain uniform wall thickness important when designing for an injection molded part? What are some considerations?

6) Discuss what causes ‘weld lines’ in an injection molded part and why these pose a problem. Sketch examples.

Below is summary of meeting minutes during the design of Single Sampling Plan. Three people attended this meeting. These are the supplier, consumer, and inspector.

The consumer said that “if the fraction of the incoming shipment is less than or equal to 0.01, I will consider the shipment as a “GOOD SHIPMENT”

After a long discussion, they agreed that the bad shipment is the shipment with probability of having nonconforming item greater than or equal 0.13.

The supplier and consumers are agreed to assign 0.05 and 0.10 to the values of their risk, respectively.

Kindly, use the above information to complete the following tasks a- Outline the OC-Curve of the potential sampling plan (only shows the important points; see the last page on the lecture). b- Design a single sampling plan (find c and n).

c- Develop the full OC curve of the above plan. Use at least 5 points on the X-axis

(five values of the fraction of nonconforming) d- What is the probability of accepting a lot with P=0.005 using the above sampling plan. Show your results on the figure developed above.

What is the probability of accepting a lot with P=0.07 using the above sampling plan. Show your results on the figure developed above.

What is the probability of accepting a lot with P=0.15 using the above sampling plan. Show your results on the figure developed above.

the plan view of a flat bottomed pontoon with all its sides vertical is shown in figure below. the displacement including the load is 28tons. it is used in sea water for which the relative density can be taken as 1.025.

1.The metacentric height if the mass centre is 400mm above the base.
2.if part of the load having a mass of 1.2 tons is to be moved 500mm to one side of centre , calculate the expected angle of tilt this would cause.

What are some of the general inspections to perform on a Hartzell propeller?

What is propeller end-play in a variable pitch propeller?

What is meant by dressing a propeller nick and stress riser?

When should a variable pitch propeller be considered for overhaul?

When and per what reference should a Harzell variable pitch propeller air charge be checked?

Calculate V and Z for methyl chloride at 100 ° C and 55bar for the ideal gas equation, by the equation of virial. Data: R = 83.14 cm 3 bar/molK; viral coefficient B equals -242.5 cm3/mol.
