1. Define the term 'force, and state clearly the effects of force. 2. What are the various characteristics of a force?
3. Distinguish clearly between resolution of forces and composition
of forces.
What are the methods for finding out the resultant force for a given system of forces?
5. State and prove parallelogram law of forces.
6. State triangle law of forces and polygon law of forces.
7. Show that the algebraic sum of the resolved part of a number of forces in a given direction.
is equal to the resolved part of their resultant in the same direction.
8. Explain clearly the procedure for finding out the resultant force analytically as well as
graphically.
