Explain Klein’s construction to determine velocity and acceleration of different links in single slider crank mechanism.
a) For velocity of different links
b) For acceleration of different links
Comparison of multiplate clutch and Cone clutch:
1.Reciprocating engine, Reciprocating compressor;
2. Whitworth quick return mechanism, Rotary engine,
3.Slotted crank mechanism, Oscillatory engine.
4.Hand pump, pendulum pump.
1.Reciprocating engine, Reciprocating compressor link 1 is fixed
2.Whitworth quick return mechanism, Rotary engine link 2 is fixed,
Adverse effect of imbalance of rotating elements:
a) Vibration, noise and discomfort,
b) Machine accuracy get disturbed,
c) Power losses,
d) More maintenance
a) Fluctuation of energy -- The difference of maximum and minimum kinetic energy of flywheel is known as Fluctuation of energy
b) Coefficient of fluctuation of energy -- - It is defined as the ratio of the maximum fluctuation of energy to the work done per cycle. It is denoted by ke = (E1 - E2)/work done per cycle
