It's my project presentation about second condition of equilibrium .... second condition of equilibrium is proved by using "Two Arm Lever Apparatus" It tells about the application of second condition of equilibrium.

1. Verification of 2nd condition of equilibrium on

2. A condition in which all influences
acting cancel each other, so that a static or
balanced situation results.
Static Equilibrium:
When a state of rest is maintained by
the object
Dynamic Equilibrium:
When a state of constant nonzero velocity
is maintained

3. Working Principle
The sum of all the torques(clock
wise & counter clock wise) acting on a
body is zero.
or
(it is necessary for the body to achieve
complete equilibrium)

4.  The moment cause by
resultant force about some
arbitrary point is equal to
the sum of moment due to
all of the component forces
of the system.

5. Parts:
1. Calibrated Ruler 2. Column 3. Base 4. Weight hangers
Mathematically :
F1d1 + F2d2 = F3d3
