H.W.#6 The above simply supported plate at 0 and x x a = = and of infinite length in the y-direction is subjected to the following loadings which vary in the x direction only: Develop the general deflection equations for the loadings ( a ), ( b ), and ( c ) using integration method and Fourier series. Evaluate x Q at 0 and x x a = = and x M at / 2 x a = . Compare both methods using 1 n = in Fourier series. Discuss the problem.
