The figure shows the shape and dimension of a small dam. Assuming the water level is at the top of the dam and that the shape of the dam is an isosceles triangle, find the total force on the face of the dam. Use 1000 kg/m for the density of water and 9.8 m/s for the acceleration due to gravity. 4m 27 m Find the width function w(y) for each value of y on the face of the dam. Place the origin at the vertex at the bottom of the dam, with the y-axis extending up in the vertical direction to the center of the the dam, and the x-axis going in the horizontal direction. Choose the correct answer. OA. W(y)=- 27 2 O c. w(y)=27 27 B. w(y)=y 27 OD. w(y)Y
