In constructing dams, the concrete is poured in lifts of approximately 1.5 m (y1 = 1.5 m). The forms for theface of the dam are reused from one lift to the next. The figure shows one such form, which is bolted tothe already cured concrete. For the new pour, what moment will occur at the base of the form per meter oflength (normal to the page)? Assume that concrete acts as a liquid when it is first poured and has a specific weight of 24 kN/m3.
