Theory of Machine Viva Questions  Kinematic Links 1. Define Machine. Answer: A machine is a device which receives energy in some available form and utilizes it to some particular type of work. 2. Define Theory of Machines. Answer: Theory of Machines deals with the study of relative motion between the various parts of a machine and the forces which act on them. 3. Define Kinematics of Machines. Answer: It deals with the relative motion between the parts neglecting the forces which are responsible for producing these motions. 4. Define Dynamics of Machines. Answer: It deals with the study of forces acting on the parts of a machines. 5. Define statics. Answer: It deals with the study of forces which act on the various parts of machines provided the parts must be in the position of rest. 6. Define kinetics. Answer: It deals with the inertia forces due to mass mass and motion considerations. 7. Define Rigid Body. Answer: It may be define...

Corrosion and its prevention Corrosion  is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical reaction with their environment. contents of notes What is corrosion ? types of corrosion details abut dry corrosion. Mechanism of corrosion. Nature of oxide formed PILLING BED WORTH RULE Rate of diffusion of metal ion.
