Problem 1.54 Solve Prob. 1.53, assuming that the structure has been redesigned to use 12-mm-diameter pins at B and D and no other change has been made. Problem 1.53 In the steel structure shown, a 6-mm-diameter pin is used at C and 10-mm-diameter pins are used at B and D. The ultimate shearing stress is 150 MPa at all connections, and the ultimate normal stress is 400 MPa in link BD. Knowing that a factor of safety of 3.0 is desired, determine the largest load P that can be applied at A. Note that link BD is not reinforced around the pin holes.
Cuando la frecuencia disminuye, la reactancia capacitiva
a. aumenta. b. disminuye. c. permanece igual. d. puede aumentar o disminuir.
Assignable cause is best described as:
a. the frequency or arrangement of data that may show repetition of numerical values. b. a cause of variation or special cause. c. a quality characteristic that varies or conforms to desired specifications. d. a cause of variation that is small in magnitude and difficult to identify; also called random or common cause.
Because it fumes at room temperatures, hydrochloric acid creates a very corrosive work environment. A machine, working in that environment, is deteriorating fast and can be used for only 1 more year, at which time it will be scrapped with no salvage value. It was purchased 3 years ago for $88,000; its operating cost for the next year is expected to be $53,000. A more corrosion-resistant challenger will cost $226,000 with an operating cost of $48,000 per year. It is expected to have a $60,000 salvage value after its 10-year ESL. At an interest rate of 15% per year, what minimum replacement value would render the challenger attractive?
What will be an ideal response?
