The motion takes place in planes perpendicular to the axis of the cylinder. In this case, the velocity distribution is (5.11.49)V(t,x)=2V∞sin(x/R). The solution of the partial differential Equation (5.11.25) at the rear critical point x = Rπ, subject to the initial condition z...
great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air 空气污染是其中一个现代世界的重大...
s most sensitive military installations. WhenPresident Dwight D. Eisenhowerformed CONAD in 1954 to provide early warning of an aerial attack from enemies such as the Soviet Union, he tasked the joint military command with scanning the skies for “reds” flying bomber planes, not a man in a ...

Most vibrations are undesirable in machines and structures because they produce excessive stresses or repeated stresses; 大多数的震动在机械和结构中是不希望存在的,因为震动会产生附加应力或者交变应力。 cause added wear;increase bearing loads; induce fatigue;create acute passenger discomfort in planes,ships...
For a domain bounded vertically by two horizontal planes, at z = 0 and z = H, we impose a zero vertical velocity there, or, in terms of the streamfunction: (14.11)ψ(0)=ψ(H)=0. Then, we recognize that the equation and its accompanying boundary conditions form an eigenvalue problem...
Lithium is the lightest metal that we have found on earth, and the planes and the fighter jets you see in the air, their body is made from lithium. The batteries you have in your mobile phones, and in your smartwatch, all are made from lithium. Button cells you see in clocks, they...
