a proposal has been made to install an industrial robot to replace the welder. The cell would consist of the robot, two welding fixtures, and the fitter who loads and unloads the parts. With two fixtures, the fitter and robot would work simultaneously, the robot welding at one fixture while the fitter unloads and loads at the other. At the end of each work cycle, they switch places. The robot would use gas metal arc welding instead of shielded-metal or flux-cored arc welding, but the welding speed would remain the same 300 mm/min. The electrode wire spool must be changed every 10 work parts, which takes 5.0 minutes and is accomplished by the fitter. Determine (a) arc-on time and (b) production rate for this work cell.

A frequent proposal has been to replace the oversight process through a system known as a “regulatory budget.” Each agency would be assigned a total cost that it could impose on the American economy, and its task would be to select the regulations that best foster the national interest subject to this cost. Can you identify any problems with the regulatory budget approach? How feasible do you believe it would be to calculate the costs of all the regulations of...

You work on a traffic management team for the city. There has been a proposal to add a new lane to a road near a busy intersection. As part of the research into whether or not to build the new lane, the team would like to know how many cars, on average, pass through this intersection at peak hour each day (5 pm to 6 pm). Your colleague has developed the hypothesis that the population mean is 886. You intend...

Tavis Robotics Corporation has developed a new robot—model FI-73—that has been designed to outperform a competitor’s best-selling robot. The competitor’s product has a useful life of 10,000 hours of service, has operating costs that average $4.65 per hour, and sells for $110,000. In contrast, model FI-73 has a useful life of 30,000 hours of service and its operating cost is $2.65 per hour. Tavis has not yet established a selling price for model FI-73. From a value-based pricing standpoint what...

It has been estimated that the concentration of CO2 in the atmosphere before the Industrial Revolution was about 275 ppmv. If the accumulation of CO2 in the atmosphere continues, then by the middle of this century, it will probably be around 600 ppmv. Calculate the pH of rainwater (neglecting the effect of any other gases) at 25oC both before the Industrial Revolution and by the middle of this century (KH = 0.033363 mol/L∙atm, pKa1 = 6.35, pKa2 = 10.33).
