a round steel alloy bar with a diameter of 0.75 in and a gauge length of 3.0 in was subjected to tension, with the results shown in the accompanying table. using a computer spread sheet program, plot the stress-strain relationship. from the graph, determine the young's modulus of the steel alloy and the deformation corrsponding to a 8225 lb load.
load(lb) Deformation 10^-4 in.2000 11.284000 22.546000 33.808000 45.0810000 56.3612000 67.66
Is the deformation equal to the strain?
A moist soil sample wights 346g.After drying at 105 degree celsius it then wights 284g. the specific gravity of the mass and of the soil is 1.86 and 2.70.
A 1 L beaker contains a material that decays at a first order rate of 0.25/day. How long will it take for the concentration in the container to be reduced to 10 % of its originalvalue
The sediment sample is 30 cm long. The porous plates on top and bottom of the sample holding it in place have a vertical hydraulic conductivity of 0.001 cm/s and each have a thickness of 10 cm.
The true bearing of the line a-b is S 88*50' W, the magnetic bearing of the line d-c is N 89*45' E. What is the magnetic declination
LANDSAT as a spatial resolution of 15m and an altitude of 700km. IKONOS has a spatial resolution of 1m and an altitude of 680km. Calculate the IFOV corresponding to the spatial resolution for sensor.
A cylindrical rod of 1040 steel originally 15.2 mm (0.60 in.) in diameter is to be cold worked by drawing; the circular cross section will be maintained during deformation.
A tensiometer is used to measure a compacted soil in the field that has a matric suction of 200 kPa under atmospheric conditions. The pore-water pressure measurement in the tensiometer reaches -99 kPa
is fabricated of two 300 mm X 25 mm flange plates and a 800 mm X 16 mm web plate. the plates are joined by four fillet welds that run continuously for the length of the girder. each weld has an allowable load in shear of 920 kN/m.
Box I contains 3 red and 5 white balls, while Box II contains 4 red and 2 white balls. A ball is chosen at random from the first box and placed in the second box without observing it's color. Then a ball is drawn from the second box.
