Shaft design features - Lab Report Example There are different designs of shafts made each day for specific machines, but most of them will not lack the identified features (Shingley, 2006). Keyway: This is a part of a system in a shaft known as a keyed joint. It comprises of the key, the key seat and the keyway. The key is used for connecting the shaft to the rotating machine and preventing relative rotation between the two. For the key to function, the rotating machine and the shaft must have a key seat and a keyway, which are the pocket and the slot in which the key fits in. Designers argue that the keyway weakens the torsional strength of the shaft since it is mostly on one side of the shaft and has sharp corners. Retaining rings: These are used during the assembling of a machine in joining the elements. They are precision engineered components applied on shafts and bores to provide a shoulder for the positioning, locating and retaining the other parts of the machine to the shaft. The two major types of retaining rings are the internal and the external retaining rings. The internal retaining rings are the rings for bores since the ring fits inside of a hole or bore. The external retaining rings are the ones for shafts since they are installed on the outside part of the shaft. The rings could be installed in axial installation, which is along the axis of the shaft or radial installation, which offers quicker assembly processes and larger clearance diameters as compared to the former. Bearings: These machine elements allow the components of a certain machine to move with respect to each other. Bearings could be found in small machines like watches and also in big machines such as skyscrapers, allowing them to move in case of an earthquake. The bearings are very important elements as without them, all machines would grind to a halt. They could either be contact or non-contact. Contact type

Rhetorical Analysis Essay Example | Topics and Well Written Essays - 1000 words - 8

Rhetorical Analysis - Essay Example A reasonable attempt is made by the print advertisement designer in order to communicate the message of the cheesy filled Cheezels crisps. Therefore, the advertisement successfully transfers the message across to the target audience. The use of objects such as a mouse trap and a Cheezels ring in place of a cheese illustrates the â€Å"Made with Real Cheese† commanding text and emphasizes the presence of real cheese as an ingredient to give an authentic cheesy taste. Furthermore, the use of colors and the focus of the image on the mouse trap and cheese with the rest of the image slightly blurred makes a stress on the cheese. The mouse trap with a cheese displays that the Cheezels ring is just like real cheese so that even a mouse can be trapped by using a Cheezels ring instead of real cheese. The mouse will be caught after it mistakes the Cheezels ring for real cheese. The background is made slightly fuzzy so as to keep the concentration and focus of the viewer on the mouse tra p and the cheese and the background objects are largely irrelevant to the whole idea of making the viewer feel the cheesy craving in his or her mouth and go purchase a bag of Cheezels. An attempt has been made to appeal to the pathos through the idea of a mouse getting killed as it mistakes the Cheezels ring for real cheese. ... The focus and positioning of the camera is done such that it enables the viewer to view the floor of the house with a wall behind that has a subtle and soothing color. The floor is where the mouse trap fixed with a Cheezels ring is placed. The single sofa at the back also demonstrates a laid-back atmosphere. The idea is that the owner of the house is in a relaxed environment where he has placed a Cheezels ring on the mouse trap in order to capture the mouse. The whole setting of the background including all its objects such as the sofa, floor, wall, mouse trap and most importantly the Cheezels ring creates a homely environment. However, no attempt is made at a logical level to prove the credibility of the â€Å"Made with Real Cheese† idea. That is, no facts or figures such as the nutritional information of the ingredients have been given to prove the cheesy flavor. The use of the images and objects particularly the mouse trap and Cheezels ring have been used as a tool to manip ulate the minds so that the viewers perceive sensory feelings that stimulate the taste center of the brain. So, the attempt has been made to persuade by stimulating their sense of taste so that its audience feels hungry and inevitably feels the urge to go buy a bag of Cheezels. Clearly, the focus is on the emotional side of human beings where the hunger provoking image of the cheesy Cheezels ring causes the viewer to develop a craving for the product. The meticulous selection of the image along with the arrangement of a tag which mentions the brand name and the slogan â€Å"Made with Real Cheese† under a bar code adds on to the creative print advertisement. The fact that the tag was positioned at the top right with the appropriate use of colors to make
