The project require hauling materials to or from the site. the following equipment is available for earthwork operations: one 5-cy heaped capacity bucket loader; a 0.5 min cycle time; 90% fill capacity one 7-cy heaped capacity bucket loader; a 0.6 min cycle time; 90% fill capacity 459-cy heaped capacity off-road trucks; a 0.5 min dump time: 100% fil capacity. loaded trucks travel through the following three sections: haul route distance grade spd speed loaded empty (mph) section 2750 700 1800 10 42 42 42 10 a. calculate the following number of cycles per loader to fill each truck number of trucks required for each loader based on the number of trucks you determine, develop a curve for the s/cy production cost vs. trucks for a range of +2 trucks. use the following hourly rates (including operator) for each piece of equipment: 6-cy capacity loader $105.00/hr 7-cy capacity loader $110.00/hr 49.5-cy off-road truck $120.00 b. determine the total time required to import/export the required materials

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
