Problem 911
A concrete dam has the profile shown in Figure P-911. If the density of concrete is 2400 kg/m3 and that of water is 1000 kg/m3, determine the maximum compressive stress at section m-n if the depth of the water behind the dam is h = 15 m.
Problem 5
If the gravity whose cross section is shown in the figure weighs 150 lb. per cu. ft., find the total weight of a section of a dam 50 ft. long.
Problem 353
The forces acting on a 1-m length of a dam are shown in Fig. P-353. The upward ground reaction varies uniformly from an intensity of p1 kN/m to p2 kN/m at B. Determine p1 and p2 and also the horizontal resistance to sliding.
Problem 266
Determine the resultant of the three forces acting on the dam shown in Fig. P-266 and locate its intersection with the base AB. For good design, this intersection should occur within the middle third of the base. Does it?
