For the following questions answer them individually
The maximum shear force in a simply supported beam of span L, subjected to a central point load, W is given by the following equation :
For simply supported beam is shown i Fig., the magnitude o if vertical reaction at ‘B’ is
If ‘A’ is the area of cross-section and ‘I’ is the moment of inertia of a given plane section, then radius of gyration (r) is given by the formula
Strain energy due to axial deformation is given by
$$ (\sigma$$ : resultant stress
P : axial load
$$\triangle$$ : deformation
$$\epsilon$$ : strain
E : modulus of elasticity)
Moment of inertia of rectangular section shown in Fig. about its horizontal centroidal axis is
Ratio of length of column to the minimum radius of gyration of the cross-sectional area of the column is known as
