Acompany receives an order to make 3 million identical machined parts. they buy the required tooling, which costs $500,000. each part requires $0.40 for material and $0.15 for labor. the indirect costs are 2.5 times the labor costs. halfway through the production run (1.5 million parts remaining), a new manufacturing method is devised that will reduce the material cost to $0.34 per part and will reduce the labor cost to $0.10 per part. this process will require $100,000 for additional tooling. should the company switch to the new method?

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
