The 60° strain rosette is mounted on a beam. The following readings are obtained for each gauge: Pa = 600(10-6 ), ?b = -700(10-6 ), and ?c = 350(10-6 ). Determine
( a ) the in-plane principal strains and
( b ) the maximum in-plane shear strain and average normal strain. In each case show the deformed element due to these strains.
The diameter of the hole is normally distributed with a mean 15 cm and standard deviation 0.025 cm, and the diameter of the piston is normally distributed with mean 14.88 cm and standard deviation 0.015 cm.
Water boils at room temperature of 25 degrees celsius when the pressure is 3.17 kPa (abs). Express this as a vaccum gage pressure (in mmHg) if atmospheric pressure is 101 kPa. Provide details of work to get a good rating.
It is estimated that 60% of the annual precipitation in a basin with a drainage area of20,000 acres is evaporated. If the average annual river flow at the outlet (runoff) is 2.5 cfs, determine the annual precipitation in the basin.
Battered piles are used on many construction projects as a permanent part of the element being constructed. Does this construction method have any play in the construction of a temporary earth retention system?
An orifice meter was calibrated for dry air at T=90 F and P=1.3 atm. The calibration data are as follow: dp(inches of water): 0,0.5,1.0,2.0,3.0,4.0,5.0 Q(ft^3/minute): 0,2.0,3.0,4.2,5.0,5.5,5.8
A hollow rectangular steel beam is 18 cm deep by 10 cm wide, outside dimensions. The walls are 2 cm in thickness. From the shear and moment diagram, the maximum vertical shear on the section is 180 kN.
A 5000 m3/day wastewater treatment plant discharges to a river with a minimum drought flow of 140 m3/min (upstream of outfall) a)What total allowable BOD (kg/day) could be discharged by the plant if the BOD in the river after initial dilution must ..
A cylindrical specimen of stainless steel having a diameter of 12.8 mm and a gauge length of 50.8 mm is pulled in tension. In the linear elastic region, a stress of 400 MPa corresponds to a strain of 0.002. Furthermore, the 0.002 strain offset li..
Two pipelines of equal length and diameters 15 cm and 10 cm respectively connect two reservoirs such that the pipelines are in parallel. The difference in water levels in the reservoirs is 3 m. If the friction is assume to be equal, the ratio of disc..
If the elastic limit of steel is 5.0 10^8 Pa, determine the minimum diameter a steel wire can have if it is to support a 69-kg circus performer without its elastic limit being exceeded.
A particle is traveling in a straight line at a constant speed of 22.9 m/s. Suddenly, a constant force of 10.7 N acts on it, bringing it to a stop in a distance of 63.6 m.
