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.
Bush's loss of his combat-readiness credential has been documented here and elsewhere in the past. But John McCain crashed five US Navy planes, and that's on the record. Moreover, he was involved in, if not instrumental to, the worst accident ever onboard a US Navy aircraft carrier -- the USS Forrestal fire. Bush, George W. (aka George Bush Junior.) Texas Air National Guard Lt. and F-102 pilot.
