Aw = 0 and M_x = 0 (no deflection, no moment along the edge)
BM_x = 0 only
CV_x = 0
Dw = 0 and w_x = 0
Answer & Solution
Correct answer: A. w = 0 and M_x = 0 (no deflection, no moment along the edge)
SS edge resists transverse deflection (w = 0) but offers no moment resistance (M_x = 0).
Since M_x = −D(w_xx + νw_yy) and w_yy = 0 along x = const where w = 0, equivalent BC is often w = w_xx = 0.
