1.Write the term paper on Relationship Between Speed and Safety in Geometric Design of Highways.

2.A light spring of a constant k=90.0 N/m is attached vertically to atable. A 2.00g balloon is filled with helium (density 0.180 kg/m^3)to a volume of 5.00m^3 and is then connected to the spring, causingit to stretch. Determine the extension distance L when the balloonis in equilibrium.

## Compute required weight of coarse aggregate per cubic yardA concrete mix with a 3-inch slump, w/c ratio of 0.50, and sand with a fineness modulus of 2.4 contains 1700 lb/yd^3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard. |

## Find what is the pressure on the soil if theta is 45 degreesA pipe is to be installed under the ground on a bed of aggregate 6 in. thick. The entire weight on the aggregate from pipe and soil above the pipe is 1800 lbs. per linear foot of pipe. What is the pressure on the soil if theta is 45 degrees |

## Fundamentals of hydraulic engineeringA stabilization pond is designed for a 35-day detention time. If the pond is maintained at a capacity of 40 acre-feet, what is theaverage gpd flow to the stabilizaiton pond? |

## Given a tree t of nodes such that each node contains agiven a tree t of nodes such that each node contains a number. a set of nodes s is an independent set of t iff no node |

## Determine what is the expected cycle service levelDemand for a particular product is normally distributed with a mean of 100 units and a standard deviation of 20 per period. if there are 120 units in inventory at the beginning of this period |

## Find appropriately sized beam such that radius is not lessThe yield stress for A-36 is 250 MPa. Using factor of safety against yield of 1.25, determine an appropriately sized beam such that the radius of curvature is not less than 140m. E= 200 GPa, G= 77.2 GPa. |

## Find what is the degree of saturation of the field sampleLet us pretend you are an earthwork construction control inspector and you are checking the field compaction of a layer of soil. After compaction in the field, the density of soil was checked by excavating part of the compacted soil |

## Calculate the heat transfer and calculate the work doneten kilograms of saturated liquid water at 5 bar is heated in a piston-cylinder assembly at constant pressure until temperature reaches 400 degrees C. A. Show the process on a T versus v diagram. |

## Show process on t-v diagram with respect to saturation lineAn insulated rigid tank is initially filled with a saturated liquid-vapor mixture of water. Initially three-quarters of the mass is in the liquid phase, the mass is 10 lbm, and the pressure is 15 psia. |
