1.Determine the runoff hydrograph that would be generated by a design 3-hr storm that generates excess rainfall at a constant rate of 10 mm/hr. assume baseflow is constant at 1.0 m3/s. (Watershed Area is 17.64 km2
2.A footing under a brick pier has dimensions 300mmx300mmx300mm deep. what is the pressure applied to the soil under the above load. How does this compare with an allowable bearing capacity of 100kPa. Does this allow for a reasonable factor of safety.
3.A simply supported beam (one end has a pin support and the other a roller support) is 10 ft long. The width of the beam is 3.5 in. The beam supports three concentrated loads (2.5 kips 2 ft from A to B, 1 kip 5 ft from A to B, and 2.5 kips 8 ft from A to B). The allowable bending stress in the wood is 1800 psi and the allowable shear stress is 120 psi. Determine the minimum required depth of the beam.
A 32000 lb airplane lands on an aircraft carrier and is caught by an arresting cable. The cable is inextensible and is paid out at A and B from mechanisms located below deck and consisting of pistons moving in long oil-filled cylinders.
Slider A moves in the horizontal slot with a constant speed v = 1.90 m/s for a short interval of motion. Determine the angular velocity of bar AB if the displacement xA = 90 mm, and the length L = 440 mm.
According to the design philosophy in the AASHTO Specifications, how does a heavy truck parked on a prestressed bridge girder effect the nominal shear resistance of the girder
A circular hatch, 2-m in diameter has its top 10-feet under water ( fresh water s.g. = 1.0), and is hinged on the bottom, and held closed on the top with a single bolt. Perform a moment balance about the hinge to calculate the force that the bolt mus..
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
Write a computer program that can be used to determine the internal shear and moment at any specified location x along the beam, and plot the shear and moment diagrams for the beam.
Calculate the (maximum) design load on a hollow AISI 1020 steel shaft with an outside diameter of 2.5 inches and an inside diameter of 2 inches. Assume a safety factor of 2.
The length of a reading room in a library is 10 m and its breadth is 8 m. Compute the distributed live load, assuming the basic value of the load to be 2873 N/m2.
Demand 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
A circular hatch, 2-m in diameter has its top 10-feet under water ( fresh water s.g. = 1.0), and is hinged on the bottom, and held closed on the top with a single bolt. Perform a moment balance about the hinge
A force is specified by the vector F = [(10)i + (150)j + (-50)k] N. Calculate the angles made by F with the positive x-, y-, and z-axes
The shift in the oxygen-hemoglobin dissociation curve with pH and PCO2 provides more oxygen available to tissues. As an example, consider the oxygen uptake by muscle tissue. The blood flow rate is 1 L/min under resting conditions.
