Unformatted text preview: 13 with x 1 , x 2 and x 3 ? b) The bending moment M now varies as a function of x 1 according to M = cx 1 The axial M stress is still give by 11 = x 3 . Again, 12 = 32 = 22 = 33 = . How does 13 I vary with x 1 , x 2 and x 3 ? Note 13 = for h = x 3 and x 3 = +h (the top and bottom surfaces of the bean are free surfaces and do not have any stress acting on them)....
