Knowing the shear and moment at any location in a beam is only useful if that information can be used to design a beam. The shear and moment need to be used to determine the stresses which can be used to find if the material will fail.implifying and rearranging gives, This equation gives the bending normal stress, and is also commonly called the flexure formula. The y term is the distance from the neutral axis (up is positive). The I term is the moment of inertia about the neutral axis.
Introduction. John McCain first entered the public spotlight as a Navy fighter pilot during the Vietnam War. Taken prisoner after his plane was shot down, he suffered five and a half years of torture and confinement before his release in 1973.
Robert Timberg, author of John McCain: An American Odyssey , who has interviewed many POWs who served with McCain, said there's no evidence that he ever collaborated with the North Vietnamese.
