8. A ½ inch diameter steel cable measuring 75 feet has a 1,000 lb load at its end, which rests on the ground. If initially the cable has no stress in it (the ground is supporting the full 1,000 lbs), determine the temerature decrease needed to make the load rise a total of 0.25 inch off the ground. E = 30 x 106 psi. Coefficient of Thermal Expansion for steel as = 6.5 x 106 in/in/deg F

The SMART technique for problem solving was introduced. In this approach, S stands for

Formulate a linear program for this problem. 1) A clothing factory can make three shoe types: A,B, and C. Their profits per shoe are, respectively, $5, $4, and $3. Type A shoes require 4 pieces of leather, and 1 piece of cloth; type B shoes require 3 pieces of leather, and 2 pieces of cloth; type C shoes require 5 pieces of cloth. The factory has 10,000 pieces of leather and 50,000 pieces of cloth available. Furthermore, the factory must produce at least 500 units of each type of shoe.

As an engineer responsible for monitoring works in the area of ​​mechanical systems, you must evaluate the following situation: a large client in the retail area has a refrigeration system where it stores some chilled or frozen products to be sold on the sales floor.Recently, the customer's maintenance department has been questioning the system's performance and requested an evaluation of the system's behavior. You went to the location and requested some information from the maintenance manager about the system, who provided the following data: - The system operates with R-134a refrigerant;- The refrigerated environment is maintained at 0°C and the external environment at 26°C;- The refrigerant flow rate in the system is 0.08 kg/s; In addition to the data provided, you carried out some tests and measured the temperature of the refrigerant fluid at some specific points in the system, such as the compressor inlet and condenser outlet, finding values ​​of 0°C and 26°C respectively.…
