moment of area of ellipse formula equation

Moment of Inertia of Circular Ring, Disc, Cylinder, Sphere and Thin Straight Rod..

Principle of Moments - If a body is in equilibrium under the action of a number of forces, then the algebraic sum of the moments of the forces about any point is equal to zero. In other words, the sum of the clockwise moments equals sum of the anticlockwise moment..

is known as the torque of the applied force about an axis which passes through O and is perpendicular to the X-Y plane. The torque measures the turning or twisting effect of force. The torque is called as the moment of force. Expression for force can be written in terms of angles also...

Dipole moment plays very important role in understanding the nature of chemical bond..

Consider a small element of the body. The element should be chosen such that, the perpendicular from different points of the element to the given line differ only by infinitesimal amounts. Let its mass be 'dm' and its perpendicular distance from the given line be 'r'. If we evaluate the product r ..

Moment of Inertia and its Physical Meaning - Consider a rigid body rotating about a fixed axis AB. Consider a particle 'p' of mass 'm' rotating in a circle of radius 'r'. The total torque on all the forces acting on all the particles of the body is: whe..

Moment of Inertia of a Diatomic Molecule - In stable equilibrium position, the two atoms in a diatomic molecule are separated by a certain distance r 0 . This distance is called intermolecular distance or bond length. Let us imagine the diatomic molecule as a system of two tiny spheres at..

Consider a rigid body rotating about a fixed axis AB. Consider a particle 'p' of mass 'm' rotating in a circle of radius 'r..

It is easier to open the door by applying force near the outer edge away from the hinge..
