Question

A crane shown in figure below is able to carry loads up to 8 tons (1 ton = 1000kg). The crane is installed on a concrete foundation with length of (a), width of 3m, and depth of 2.4m.

A weight of 5 tons is being used as a stable block at the left end. The weight of crane itself is 18 tons and it is being applied at the center of C (0.6 m from center of foundation). The unit weight of concrete is 2.2 ton/m^3.

Determine the foundation length (a) in order that NO tensile stress occurs under the foundation (at the soil level).

How much is the maximum compressive stress in foundation? (use the calculated (a) from previous part in order to find the maximum compressive stress)
