GIVEN: A simple way to model air pollution over a city is with a box model that assumes complete mixing and limited capability for the pollution to disperse horizontally or vertically except in the direction of the prevailing winds (for example, a town located in a valley with an inversion layer above it). Consider a town having an inversion at 250 m, a 20-km horizontal distance perpendicular to the wind, a windspeed of 2 m/s, and a carbon monoxide (CO) emission rate of 60 kg/s .Assume the CO is conservative and completely mixed in the box.

FIND: What would be the CO concentration in the box?

## Determine the load p if the total elongation of the systemA 0.25 in diameter copper rod BC is securely attached between two identical 1 in diameter steel rods (AB and CD). Find the load P if the total elongation of the system is measured to be 0.0312 in. Esteel= 29,000ksi, Ecopper=17,000ksi. |

## Find how many assemblies the inspector may inspect per minA grievance has been filed by the union at Dorben Co. regarding the final inspection station, in which the operator slightly lifts a 20 lb assembly, examines all sides, and, if acceptable, sets it back down on the conveyor, where the assembly goes.. |

## Prove that the forces are equal and that the lines of actionthis cuts it down to a single force that you have to solve for, regardless of what type of member it is. Prove that the forces are equal and that the lines of action are along an angle theta. HINT: Use to do equations of equilibrium. |

## Design a curve for the highway by computing the radiusThe PI is at station 250+50, the design speed is 65mi/h, and a maximum superelevation of 0.07 ft/ft is to be used. If the central angle of the curve is 38 degrees, design a curve for the highway by computing the radius and stationing of PC and PT. |
