A cylinder 4 in. internal diameter and 1 in. thick, has an external sleeve 1 in. thick shrunk on it. The shrinkage is such that, when the internal fluid pressure (fluid in the cylinder) is applied, maximum shear stress both in the tube and sleeve is 16000 psi. Calculate the fluid pressure, and determine the pressure between the sleeve and cylinder when the fluid pressure is absent.
A cylindrical soil sample fails under an axial vertical stress of 160 kN/m^2, when it is laterally unconfined. The failure plane makes an angle of 50 degrees with the horizontal.
A construction company requires to know how much of additives A and B to use to prepare concrete to be used in a freezing environment (northern location). The concrete mix should contain a minimum concentration of nitrate and sulphate.
suppose a steel material of specific gravity of 7.8 is attached to a wood of specific gravity 0.8. if it is required that the material does not sink or rise when left in static water, what should be the proportion of the volume of the steel to tha..
(a) Determine the magnitude of the projected components of F acting parallel Fp and normal Fn to line OA. (b) Express these components Fp and Fn in Cartesian vector notation.
Measurements of groundwater concentrations of silica (SiO2) in mg/L, were made at a sample of 12 wells in Birmingham. The sample mean concentration was 61.3 and the standard deviation was 5.2.
What percent increase in shear force would be experience on the flat sides of a 40 ft long truck trailer as the truck speed increases from 65 mph to 75 mph. Kinematic viscosity of the air is 1.6x10^4 ft^2/s.
Two towers A and B are located on flat ground and their bases have equal elevations above sea level. A person on tower A whose eye level is 26.0 ft above the ground can just see the top of tower B, which is 105 ft above the ground. How far apart a..
at s=0 the driver applies the brakes hard enough to cause the car to skid. Assume that the car keeps sliding until it stops, and assume that throughout this process acceleration is a= -7.4556. compute the car's stopping distance and time.
Data obtained from aerial photography showed six vehicles on 900 ft-long section of road. Traffic data collected at the same time indicated an average time headway of 4.3 sec. Determine (a) The density on the highway. (b) The flow on the road, and
two forces applied as shown to a hook support. knowing that the magnitude of P is 35 N, determine by trigonometry the required angle if the resultant R of the two forces applied to the support is to be horizontal and the corresponding magnitude of..
The cable from point A to point B exerts a 900 N force on the top of the television transmission tower that is represented by the vector F. Express F in Cartesian vector form using the coordinate system.
a steel tape 30m long at a temperature of 65ordmf when lying horizontally on the ground. its sectional area is 0.082
