## Sample ME6505 DYNAMICS OF MACHINES Important questions:

1. Distinguish between space diagram and free body diagram

Space Diagram is a graphical representation of the system. It generally shows the shape and size of the system, the weight, the externally applied loads, the connection and the supports of the system. Free body diagram is a sketch of the isolated or free body which shows all the pertinent weight forces, the externally applied loads, the reaction from its supports and the connections acting upon
it by the removed elements.

2. Define Static force analysis.

If components of a machine accelerate, inertia is produced due to their masses. However the magnitudes of these forces are small compared to externally applied loads. Hence the inertia effects due to masses are neglected. Such an analysis is known as static force analysis.

3. Define force and applied force.

Force is a pull or push, which acts on the body changes or tends to change the state of rest or uniform motion of the body. The external force acting on a system of body from outside the system are called as applied forces.

4. Give any 3 advantages of free body diagram

?They assist in seeing and understanding all aspects of problem
?They help in planning the approach to the problem
?Theymake mathematical relations easier to the problem.

5. When will the three force member is in equilibrium.

The resultant of forces is zero.
The line of action of the forces intersect at a point.

6. When will the two force member is in equilibrium.

?The two forces are of same magnitude.
? The forces acting along same line.
? The forces are in opposite direction.
