which moves relative to some other part is known as a kinematic link (or simply link) or an element. A link may consist of several parts‚ which are rigidly fastened together‚ so that they do not move relative to one another. For example‚ in a reciprocating steam engine‚ as shown above‚ crank‚ connecting rod‚ piston‚ engine frame and main bearings are the four links. A link or an element need not to be a

Question 1 A) Radial cam with a knife edge follower In the radial cams‚ the working surface of the cam is designed such that follower moves in a plane perpendicular to the axis of the cam performing a reciprocating motion. The knife-edge followers are simple in construction. The contacting end of the follower with the cam has a sharp knife edged hence it is called so. The motion between the cam and follower is sliding. It is not used in practice because small area of contact surface results

rod it will rotate in the nut and in turn moves the movable jaw. Here the rotary motion is converted into reciprocating motion. In Hydraulic type’s one end of the piston rod is connected to the movable jaw and the piston slides in the cylinder. Here the hydraulic fluid actuates the movement of the piston; this in turn actuates the movable jaw. Here the principle movement is only a reciprocating movement. Pneumatic type is same as the hydraulic type. Here instead of hydraulic fluid‚ air is used. LINE

Running‚ Bob screamed‚ “Billy run! He’s behind us! Don’t stop!” As they’re running they saw the bridge next to the beach in Los Angeles. Billy started running faster and faster then he finally caught up with Bob. They both looked back and saw the man in the dark. They could barely see the beach in the fog. Still running‚ Bob screamed‚ “I can see the beach house Billy.” The house was approaching them in the fog. The man in the dark came out of nowhere with his super sharp axe dripping with dark

The poem begins with a vivid imagery of sensations. The onomatopoeia of line one „The buzz saw snarled and rattled in the yard“ is redoubled in line seven. „And the saw snarled and rattled‚ snarled and rattled.” The assonance emphasizes the sound of the sawing machine. The cutting noise of the saw is compared to a wild animal‚ like a tiger‚ which shows a personification. Both words “snarled” and “rattled” resonate with sound and fury. Repetition is also used in “Electricity comes to Cocoa Bottom”

Diamond Wire Saw Machining ABSTRACT The process monitoring and mechanics of fixed abrasive diamond wire saw machining are investigated in this study. New techniques to affix diamond particles to a steel wire core have advanced to make this process feasible for the machining of ceramics‚ wood‚ and foam materials. Developments in fixed abrasive diamond wire machining are first reviewed. Advantages of using fixed abrasive diamond wire machining are then introduced. The process monitoring and signal

shaft by which reciprocating motion is imparted to or received from the shaft. It is used to convert circular motion into reciprocating motion‚ or vice-versa. The arm may be a bent portion of the shaft‚ or a separate arm attached to it. Attached to the end of the crank by a pivot is a rod‚ usually called a connecting rod. The end of the rod attached to the crank moves in a circular motion‚ while the other end is usually constrained to move in a linear sliding motion. In a reciprocating piston engine
