1.A 6ft wide, 10ft high vertical rectangular gate has its top edge 6ft below the water level. it is hinged along its lower edge. what force, acting on the top edge, is necessary to hold the gate shut?

2.Two vertical forces are applied to a beam of the cross section shown. Determine the maximum tensile and compressive stresses in portion BC of the beam.

3.Base course aggregate has a target dry density of 119.7 lb/cu ft in place. It will be laid down and compacted in rectangular street repair area of 2000 ft X 48 ft X 6 in. The aggregate in the stockpile contains 3.1 percent moisture. If the required compaction is 95 percent of the target, how many tons of aggregate will be needed?

## What will be gage reading if atmospheric pressure increasesa bourdon pressure gauge attached to the outside of a tank containing air reads 77.0 psi when the local atmospheric pressure is 760 mm Hg. what will be the gage reading if the atmospheric pressure increases to 773 mm Hg |

## Determine elevation of point b from the elevation of a pointTo determine the elevation of a point B from the elevation of a point A, which is 511.6 ft. When the transit was set up over the point A, the height of the transverse axis above that point was 4.92 ft. |

## Determine the tension in cable cd over the smooth square rodMember ABC is supported by cable CD and a square collar at A that fits loosely over the smooth square rod. Determine the tension in cable CD. The smooth rod is fixed at its base and cannot rotate. |

## Integrate the rate equation and solve for the concentrationInvestigators have determined that the rate equation for bacterial kill in batch chlorine contact chambers is: rxn rate = dC/dt=-kCt where C is the concentration of bacteria, k is the rate constant, and t is time. |

## Principal stresses and calculate the max shear stressAt a section in a beam the tensile stress due to bending is 70 N/mm 2 and there is a shear stress of 25 N/mm 2 . Determine from first principles, the magnitude and direction of the principal stresses and calculate the max shear stress. |

## Select the required commercial size of the rod required toTwo forces are applied as shown to hook support. Knowing that the magnitude of P is 35 N, determine by trigonometry (a) the required angle a if the resultant R of the two forces applied to the support is to be horizontal, (b) the corresponding magnit.. |

## Estimate the volume of recharge during the rainy seasonA volume of 1.5x106 m3 of water is then pumped out of the aquifer resulting in a decrease of the groundwater level to 208.8 m. Assuming that the water table in the aquifer responds similarly |

## Identify the planes on which they act by drawing theFor the case of the uniaxial compression, determine the maximum shear stresses that exist at that piont. Identify the planes on which they act by drawing the orientation of the element for these shear stresses. Show all stresses that act on the eleme.. |

## Which of the techniques discussed in class would appropriateYou want to make sure that the hill slope -the earth of which has also been excavated by your teams and the organic soil and vegetation removed- will remain stable for the safety of your workers. |

## Calculate the change in vertical effective sress on the roofThe foof of the culvert will be located 3 m below ground surface. Currently the groundwater level is at ground surface. But, after installation of the culvert, the groundwater level is expected to drop 2 m below ground surface. |

## Determine the minimum number of coins rich man hasAccording to his will: First give one coin to manager. 1/5th of the remaining to the elder son. Now give one coin to the manager and 1/5th of the remaining to second son and so on. |

## Horizontal curve on a single-lane highwayA horizontal curve on a single-lane highway has its PC at station 124 + 10 and its PI at station 131 + 40. The curve has a superelvation of 0.06 ft/ft and is designed for 70 mi/h. What is the station of the PT? |
