EXPERIMENT. No.7

                                                  EXPERIMENT. No.7 10.0 Questions for confirmation of learning 1 . The Inertia governors have an advantage over the centrifugal governor because they give more rapid response to the change of load since the displacement of the governor balls is determined by the rate of change of speed of the engine shaft. However it is not possible to achieve the complete balance of revolving parts of the inertia governor. Due to this disadvantage of the inertia governors , these are not used usually compared to centrifugal governors. 2 . Spindle, Flyballs, sleeve, arms, links, bell crank lever, bevel gear. 3 . decreases. 11.0 The Inertia governors have an advantage over the centrifugal governor because th...

EXPERIMENT No. 1

                                                       EXPERIMENT No. 1 9.0 Observations : In witworth quick return mechanism slotted bar is pivoted in between and it oscillates on that pivoted point. Where as in crank and slotted lever quick return mechanism slotted bar is pivoted at the lower end and it oscillates around that pivoted point. 10.0     Questions for confirmation of learning: 1. Hand pump to fetch water from underground 2. Four links are required to form a constrained kinematic chain. 3. Motion in a definite direction is called as constrained motion. Slider and slotted bar, Crank and slider   have constrained motion in crank and slotted bar mechanism. 4. Four links and four pairs ...

EXPERIMENT No.9

EXPERIMENT No.9 08:   A Observations: Clutch components and their functions Sr no Part Name Function of part 1 Clutch Plate To connect driving and driven shafts and thereby transmitting power. 2 Pressure plate To exert pressure and to grip the clutch plate between flywheel   And pressure plate. 3 Spring The plates are alternately fitted to the engine shaft and gear box shaft. They are firmly pressed by strong coil springs and assembled in a drum 4 Driven shaft To transmit the motion to the wheel 5 Driving shaft To transmit motion from an engine shaft to flywheel and then to rear wheel 8.0:   B                        ...
