For the loading given in the figure below, two statements ( $${\rm I}$$ and $${\rm II}$$ ) are made.

$${\rm I}.$$ $$\,\,\,\,\,\,\,\,\,$$Member $$AB$$ carries shear force and bending moment
$${\rm II}.$$ $$\,\,\,\,\,\,\,$$Member $$BC$$ carries axial load and shear force

Which of the following is true ?

In the propped cantilever beam carrying a uniformly distributed load of $$w$$-$$kN/m,$$ shown in the following figure, the reaction at the support $$'B'$$ is

The shear modulus (G), modulus of elasticity (E) and the Poisson's ratio ($$\mu$$) of a material are related as

Calculate the shape factor for the $$T$$-section shown in the following figure made up of two plates $$100\,\,mm \times 10\,\,mm.$$ What will be the load factor if the permissible stress in bending is only $$2/3$$ of the yield stress $$\left( {{\sigma _y}} \right)$$
