Question

3:)In the figure, the hollow square section chimney made of stone brick is under the effect of a triangle radiated force, which is assumed to be equivalent to the wind load. Maximum intensity of the load per unit area q₀ = 1.2 kN / m². Specific weight of stone brick p_t=15 kN/m³ pressure safety stress in brick (ϭ_safe)_z=200 kN/m². Chimney cross section dimensions a = 2.5 m, b = 2 m . Calculate the maximum height h at which the chimney can be built so that no tensile stress occurs between the floor and the chimney, and find the normal stress distribution at the base of the chimney (Note: neglect the shear effect.)
