Force is one type of agent which produce or tends to produce, destroys or tends to destroy the state of the body. It is the most important topic for understanding the state of any physical body. There are various types of forces like gravity forces, frictional forces, magnetic forces, ionic forces but behalf of this all the forces divided by their direction occurring on the same plane and different planes are basically explained in this video. The plane are being differ by the direction of axis, basically there are three types of axis like; x-axis, y-axis and z-axis. All the axis have there planes. One the basis of these there are various types of forces like coplanar forces, non coplanar forces, concurrent forces, non concurrent forces, etc. Mainly the resultant force example are being solved in course. In this course you will get to understand about the introductory portion of the force, basic definition, types of forces and explanation of types of forces. Law’s like law of parallelogram, law of triangle, law of resolution and lami’s theorem. Derivation of laws, explanation of equation of all laws. Free body diagram to convert complex physical body into simpler sytem of forces to calculate the resultant force by using lami’s theorem.
