For the following questions answer them individually
The forces acting normally on the cross section of a bar shown in the figure given below introduces
If a concrete column 200 x 200 mm in cross-section is reinforced with four steel bars of 1200 mm2 total cross-sectional area. What is the safe load for the column if permissible stress in concrete is 5 N/mm2 and Es =15 Ec?
A steel rod of sectional area 25 sq. mm connects two parallel walls 5 m apart. The nuts at the ends were tightened when the rod was heated at $$100^\circ$$ C. If $$\alpha$$ steel = 0.000012/$$C^\circ$$, Esteel = 0.2$$MN/mm^{2}$$, the tensile force developed at a temperature of $$50^\circ$$ C is _____
The ratio of tangential and normal components of a stress on an inclined plane through $$\theta*\circ$$ to the direction of the force is _____.
At any point of a beam, the section modulus may be obtained by dividing the moment of inertia of the section by _____.
