DESCRIPTION
TRANSCRIPT
A machine receives energy in some available form and uses it to do some particular kind of work
Mechanics of Machinery or Theory of Machines – comprises the study of the relative motion between the parts of a machine and the study of the forces which act on those parts◦ The study of relative motion between the parts is known
as kinematics◦ The study of the forces which act on the parts is known
as dynamics Statics deals with the forces which act on various parts when
those parts are assumed to be without mass
Kinetics deals with the inertia forces arising from the combined effect of the mass and the motion of the parts
In a reciprocating engine◦ the piston reciprocates inside the cylinder by pressure◦ reciprocating motion of the piston is converted into
rotary motion of the crankshaft It is afterwards necessary to examine the inertia
forces which act on each part, since the parts are subject to acceleration and retardation during the working of the engine
Mechanisms – velocity, acceleration, and inertia forces
Crank Effort Diagrams Balancing of Rotating and Reciprocating Masses Study of Cams Brakes and Clutches Belt, Rope, and Chain Drives Study of Governors Toothed Gearing
Epicyclic Gear Trains Study of Gyroscopes Free Vibrations Transverse Vibration of Beams Critical Speed of Shafts Torsional Vibrations Damped and Forced Vibrations Forced-Damped Vibrations
