During the construction of a dam, concrete was poured into a lift of approximately 1.8 m (yı = 1.8 m). The shape of the front of the dam is reused from level to level. The figure shows one such shape, which is bolted to the cured concrete. New pour level Cantilevered form 60° Old pour level Bolts Cured concrete Figure 1: Schematic for a dam's base. For the new pour, assuming that concrete acts like a liquid when it is first poured and has a specific weight of 20 kN/m³, do the following: a. Describe the forces acting on the form due to the concrete. b. Describe the forces acting on the form due to the air. c. Determine the position of the center of pressure on the form.
