Principle of Moments
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 h..

It is easier to open the door by applying force near the outer edge away from the hinges.
When we apply the force the door turns on its hinges. Thus a turning effect is produced when we try to open the door. Have you ever tried to do so by applying the force near the hinge? In the first case, we are able to open the door with ease. In the second case, we have to apply much more force t..
Levers of first order
The distance AF is called the effort arm and the distance BF is called the load arm. If the lever is in equilibrium, then by applying the principle of moments about the fulcrum, we get Clockwise moment = Anticlockwise moment Effort x Effort arm = Load x Load..

The physical balance used in the school laboratory is pivoted in the middle with equal arms. The two scale pans of equal weights are hung from the upper edge of wedge shaped supports at either end of the beam. When the beam is raised for weighing, it swings freely about the lower edge of a wedge s..

>To increase the turning effect of force, it is not necessary to increase the magnitude of the force itself. If the total external torque on the system is zero, its angular momentum remains constant. This is known as the principle of conservation of angular momentum. If angular momentum r..
Wheel and Axle
Steering wheels, spanner, screw drivers and bicycle pedals all use the principle of wheel and axle. Solved Examples: Example 1 : Figure below shows the use of a lever to lift a boulder of weight 3000 N by applying a suitable effort at C. If AB = 1 m and BC = 6 m, calculate the effort requ..

According to Heisenberg's uncertainty principle, it is impossible to describe the exact position of an electron at a given moment in terms of position, we can speak of most probable regions where the probability of finding an electron in the space around the nucleus of an atom ..
