A cantilever retaining wall is required to support a cut near a residential area. A preliminary geometry of the wall is shown in Figure P15.24. A masonry wall 1.2 m high will sit on top of the wall, centered. The masonry wall load (including construction loading) is 9 kN /m and the uniform loading from the home site is 10 kPa. The wall rotation is limited to 0.0005 Ho (Ho is the height of the wall). Check the adequacy of the wall. Determine a suitable wall geometry if the given geometry is unsatisfactory. Sketch a drainage scheme for the wall. Neglect wall friction. (Hint: The tolerable wall rotation is very small; it is less than the wall rotation to mobilize the active earth pressure.)
determine the maximum horizontal distance that a projectile will have at a height of 60 m above the orgin if it is fired at an angle at 70 degrees from the horizontal with a velocity of 50 m/s
A two story school has interior columns that are spaced 15 ft apartin two perpendicular directions. If the loading on the flat roof isestimated to be 20 lb/ft^2 determine the reduced live loadsupported by a typical interior column at
A level is set up midway between two wood stakes that are about 300 feet apart. The rod reading on Stake A is 9.65 ft and the reading on stake B is 4.23 ft. The level is then set up 6 feet in front of stake B.
