STATICS OF PARTICLES
2 – marks question and answers
1. Define particle.
A body of negligible dimension is called a particle.
, Define rigid body.
The body is always rest without application of force.
2. Write the conditions of equilibrium of rigid body.
1. Total vertical force equal to zero, 2. Total horizontal force equal to zero and 3. Total moment equal to
zero.
3. State principle of transmissibility.
Force is transverse anywhere on the body without change of line of action the effect will be same.
4. Define resultant force.
h.
A system of forces acting on the body that all the forces are replaced by single equivalent force that force is
ec
called resultant force.
M
5. What is free body diagram?
f./
The force, force directions and where it is act on the body that information indicated diagram is called free
ro
body diagram.
