1.Two tangent intersect at angle of 30 degree ad 40 minute at sta 90+10 and are joined by a 4 degee 30 minute curve. using the tabla for radii and dflection distance what is the tangent distance if the degree of curve is base on a 100-ft chord ? wich one is the right awnser is A 349.00ft or B349.11 or C 349.20 or D 349.50 wich one is correct
2.A motorcycle starts from rest at time t=0. The force on it from t=0to 30 seconds is F=300-9t. The combined mass of the motorcycle andthe rider is 225 kg. Use the Impulse and Momentum method to findthe magnitude of the velocity at t=30 seconds.
A sample of natural glacial till was taken from below the groundwater table. The water content was found to be 52%. Estimate the wet density, dry density, buoyant density, porosity and void ratio. Clearly state any necessary assumptions.
Design a riveted end plated Connection between a beam ISHB-300 and the flange of the Column ISHB-200 to transfer a vertical factored shear of 125 kN and a factored hogging bending moment of 125kNm.Use Shop rivets of 20mm dia.
An exhaust system was added to provide 1 air exchange per hour (ACH) in the crawl space. The outdoor concentration of radon is 1 pCi/L. Estimate the radon concentration in the crawl spce (in pCi/L).
The mass flow rate of steam into a steam turbine is 5 kg/s . The turbine has a heat loss of 5 kj/s. if the velocity of the refrigerant is to be limited to 2 m/s, what is the minumum allowable pipe diamter
To avoid the salinization of soil in a farming area, parallel drainage canals are to be installed to maintain the water table at a depth of at least 4m below the ground surface. It is thought that no evapo-transpiration would occur below that dept..

A storage pile of crushed rock is 100ft by 100ft square at its base and 50 ft by 50 ft square on the top. The pile is 25 ft high. What is the volume of rock in the rock pile
The dimensionless henry's constant for TCE at 25 degrees celsius is 0.4. A sealed glass vial is prepared that has an air volum of 4mL overlying an aquesous volume of 36mL.
The overhang beam has been fabricated with a projected arm BD on it. Draw the internal shear force, bending moment, and normal force diagrams for the beam ABC if it supports a load of 800 lb.
The driver of a car traveling up a 2% grade at an initial speed Vo applied the brakes abruptly and the vehicles slid to a complete stop at an average deceleration of 8 ft/s^2. Was the pavement wet or dry
A horizontal curve is being designed for a new two-lane highway(12-ft lanes). The PI is at station 250 + 50, the design speed is 65 mi/h, and a maximum superelevation of 0.07 ft/ft is to be used.
