Assume that we are working with an aluminum alloy (k = 180 W/moC) triangular fin with a length, L = 5 cm, base thickness, b = 1 cm, a very large width, w = 1 m. The base of the fin is maintained at a temperature of T0 = 200oC (at the left boundary node). The fin is losing heat to the surrounding air/medium at T? = 25oC with a heat transfer coefficient of h = 15 W/m2oC. Using the...

BridgeRock is a major manufacturer of tires in the U.S.. The company had five manufacturing facilities where tires were made and another 20 facilities for various components and materials used in tires. Each manufacturing facility produced 10,000 tires every hour. Quality had always been emphasized at BridgeRock, but lately quality was a bigger issue because of recent fatal accidents involving tires made by other manufacturers due to tread separation. All tire manufacturers were under pressure to ensure problems did not...
