A masonry dam 4 m on top, 16 m at the bottom and 24 m high has water 21 m deep on its vertical side. Neglecting hydrostatic uplift, what is the soil pressure at the heel? Assume weight of masonry as 2400 kg/m³.

2. A dam consists of continuous flat-plat barriers whose masses are negligible. Supporting struts A, B, C and D are placed every 3 metres along the dam structure. A mud sample drawn up to the surface has a density of 1.6 Mg/m³. Determine the force in struts Cand D. All joints can be assumed to be hinged. FRESH WATER 3m B D MUD 3m A 3m

a building will have a sitting wall on the north side of the building to allow for seating during outdoor season. the wall will be 1.5 meter tall. what is the minimum width of the wall to ensure that it will not slide or overturning? the soil behind the wall is a sand with Gamma dry= 18.3 kN/m^3 , gamma buoyant =11.5 Kn/m^3 , gamma water= 9.81 kN/m^3 and phi= 36 degrees. the water table is 0.5 m below the ground surface. to enhance the aesthic value of the seating area, the architect has asked that the wall he made of granite ( gamma granite= 25 kN/m^3.
