A simply-supported beam of length $$3L$$ is subjected to the loading shown in the figure.

It is given that $$P = 1$$ $$N,$$ $$L = 1$$ $$m$$ and Young’s modulus $$E = 200$$ $$GP$$a. The cross-section is a square with dimension $$100$$ $$mm$$. The bending stress (in Pa) at the point A located at the top surface of the beam at a distance of $$1.5L$$ from the left end is _____________ .

(Indicate compressive stress by a negative sign and tensile stress by a positive sign).

For the component loaded with a force $$F$$ as shown in the figure, the axial stress at the corner point $$P$$ is

A simply supported beam of span length $$6$$m and $$75$$ mm diameter carries a udl of $$1.5$$ kN/m

What is the maximum value of bending moment?
