All the members of the rigid frame shown in Figure S11.4are of uniform section, and the frame is hinged at supports 1 and 5. The dimensions and loading are indicated on the figure, and the Euler load for member 12 is 8 W . Determine the load factor against collapse by elastic instability of the frame in its own plane.
A layer of clay 5 m thick overlies a deposit of sand 5 m thick, which is underlain by rock. The water table in the sand is sub- artesian with a level at 2 m below ground level
A water sample has bucarbonate concentration of 220 mg/l ( HCO3- )and the PH of the water is 7.9 > Express the approximate alkalinityof this water as mg/l of CaCO3
what is the pressure applied to the soil under the above load. How does this compare with an allowable bearing capacity of 100kPa. Does this allow for a reasonable factor of safety.
