The resultant of two equal forces P making an angle $$\theta ,$$ is given by

If a number of forces are acting at a point, their resultant is given by

The linear acceleration (a) of a body rotating along a circular path of radius (r) with an angular acceleration of $$\alpha $$ rad/s2, is

Moment of inertia of a circular section about an axis perpendicular to the section is

According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through center of gravity (i.e. $${I_{\text{P}}}$$) is given by (where, A = Area of the section, $${I_{\text{G}}}$$ = Moment of inertia of the section about an axis passing through its C.G. and h = Distance between C.G. and the parallel axis.)

For any system of coplanar forces, the condition of equilibrium is that the
