Problem 1: Determine the internal forces at point J for the structure shown, where member BD can only carry axial forces. Take the dimension a = 160mm and the external load P = 450N
Problem 2: Given the beam shown below, determine the shear force and bending moment at point C. Given the dimensions a = 3 m, b = 6.8 m and c = 2m, and the load intensities e = 9.5 kN/m and f = 2.5 kN/m.
a silty material is to be used to fill an earth damn. How much water must be added to bring the water content of each ton (2000 lb) of the material to 35% if the original watter content is 11.4%
A cast iron water main 14m long of 600 mm inside diameter and 30 mm wall thickness runs full of water and is supported at its ends. Calculate the maximum stress in the metal if density of cast iron is 7200 kg/m and that of water is 1000 kgm.
The coordinates for Point A, Point B and Point C are 5859.28N, 9331.56E and 8501.95N, 7911.60E and 10,500.00N, 8000.00E respectively. An angle right of 220°31'00" is turned when the backsight is B
At the inlet, the pressure is 6 MPa, the temperature is 500 degrees C, and the velocity is 20 m/s. At the exit, the pressure is 0.5 MPa, the quality is 0.95(95%), and the velocity is 75 m/s. The turbine develops a power output of 2500kW.
A 12-in diameter concrete culvert (n=0.013) flows half full and is constructed on a grade of 0.5 %. What would be the expected flow velocity
Two marbles are drawn in succession from the box containing 10 red, 30 white, 20 blue, and 15 orange marbles. replacement being made after each drawing. Find the probability that is:
1.How long is the irrigation boom (in feet) from the center pivot to its farthest extent. 2.If the irrigation boom makes 4 full revolutions in a day, how many miles does the end of the boom travel in 4 days.
A steel I beam is supported by a pin at point A and a rocker at B, and a cable applies a 2000lb force. The beam is uniform and weighs 26 lb/ft. Determine the support reactions.
A diver is planning to salvage a Spanish galleon located in 200 feet of water. He plans to use a diving suit that will be supplied with air from a hose (assume this to be amply sized) connected to a compressor that he will locate in his boat on the s..
A process in a plant is to be revised such that the air flow rate through a system will increase from 8000 cfm to 10,000 cfm. The existing fan runs at 1600rpm and provides 6.0 in. H2O SP.
A tracer study was conducted to assess groundwater velocity and showed that a slug of a conservative tracer took 34 days to travel the 10-m distance between two wells.
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.
