- An 87.5 kg fisherman sits at the center of the boat, which has a uniform width and a weight per linear foot of 4.1 lb/ft. The boat is 13 m long. Assume that the water exerts a uniform distributed load upward on the bottom of the boat. a. What is the applied load (lb) applied to the boat due to the weight of the fisherman? Round up to the next whole value.b. Using the applied load at Item 9.a, what is the maximum shear force (lb) exerted on the boat?c. What is the maximum bending moment (lb-ft) exerted on the boat?d. At what distance from the left side of the boat the maximum bending moment occurs?A triangular dam is shown in the figure, base is 6-m and height is 8-m. Compute for the factor of safety against sliding and overturning. Unit weight of concrete is 23.54 kN/cu.m. Consider 1 meter length strip. Disregard hydrostatic uplift pressure. The coefficient between the dam and the foundation is 0.8. hA long retaining wall is braced by wood shores set at an angle of 308 and supported by concrete thrust blocks, as shown in the first part of thefigure. The shores are evenly spaced at 3 m apart. For analysis purposes, the wall and shores are idealized as shown in the second part of the figure.Note that the base of the wall and both ends of the shores are assumed to be pinned. The pressure of the soil against the wall is assumed to be triangularly distributed, and the resultant force acting on a 3-meter length of the walls is F =190 kN. If each shore has a 150 mm 3150 mm square cross section, what is the compressive stress σc in the shores?
