Unformatted text preview: the slab is where A m ( t) = A t ( t) + A b ( t ) + A s ( t) Euler’s First Law for a Thin Slab Cont. Averaging Euler’s First law over the slab gives: n At
As µ Ab n As the thickness of the disk shrinks to zero, we get (Newton’s Third Law) RelaNonship Between the TracNon Vector and the Unit Normal To establish the rela)onship we consider a control volume in the shape of a Small tetrahedron with three mutually orthogonal f...
