In the figure shown, find the width b of the concrete dam necessary to prevent the dam from sliding. The specific gravity of concrete is 2.4 and the coefficient of friction between the base of the dam and the foundation is 0.4. Use 1.5 as the factor of safety against sliding. Solve also the FS against overturning. 4.5 m 6m

Solve b

A column is made of steel and concrete, if the normal forces on steel and concrete are 6.8kip and 145kip and the allowable stresses of steel and concrete are 36ksi and 5.5ksi, and the cross sectional areas of steel and concrete are 0.3068in^2 and 45.5456in^2, determine whether the still or concrete will fail when given a yield factor of safete of 1.69

A steel column with the cross section shown has a 14.9-ft effective length. Using Allowable Stress Design, determine the largest centric load that can be applied to the column. Use øy= 36 ksi and E = 29 × 106 psi. in. H 6 in. 10 in. in. The largest centric load that can be applied to the column is kips.
