CHAPTER 2

LITERATURE REVIEW

2.1 Introduction

Cam is a versatile, specially shaped part of a machine that is always in contact with a member a called the follower. The name cam should not be confused with the common abbreviation cam for camera and camcorder, both used in the fields of photography and video, nor with the acronym CAM applied to computer applied to computer-aided manufacturing, which utilizes computational facilities for machinery fabrication of all kinds.

Many different types of cam profile are designed and manufactured depending on a machine’s requirements (P.W Jensen, 1987). Cam is a part of a rotating wheel or shaft that strikes a lever at one or more points on its circular path. The cam is in most cases merely a flat piece of metal that has had an unusual shaped or profile machined onto it.

Many studies on the cam mechanisms concern the problem of vibrations. As machine speed increases the problem of vibrations of the cam mechanism has the more significant importance. The vibration level has the influence on the wear rate, noise level and service life of the cam actuated machines and devices and also to the precision operation of machines. Because of that it is important to understand the cause of vibrations and provide means to control or to minimize unwanted vibrations so that desirable system response characteristics may be predicted and obtained.

Cam follower mechanism are found in almost all mechanical device and machine for example in agriculture, transportation equipment, textiles, packaging, machine tools, printing press, automobile internal combustion engines, food processing machines, switches, ejection molds, and control systems, and more recently in micro machines such as micro electromechanical system[MEMS].

    The licensing contract is only three years, the Bar Maisse is not famous, and the sales is difficult to be estimated, therefore, we suspect if licensing could meet the expectation of rapid growth. The cost of licensing is lower in comparison to joint venture and direct investment, but the royalty is only 5% of gross sales. The growth of CAH might not be significant.

    The argument from design is an analogy and works by comparing the universe to an object. An example of the comparison would be to say the world resembles a car. All cars have creators, therefore, the world has to have a creator, and that must be God. The argument concludes by saying by observing the world we can gather evidence that the intelligence of a human that creates a car, bike or some other item resembles, in a less perfect form, God. However, Hume thinks this argument fails.…

    The author attempts to prove that the pre-Romanesque relief on the facade of the parish church of St George in Keutschach (Hodiše) in Austrian Carinthia is a depiction of the Orion constellation. He justifies his theory with historical and art-historical facts. The main emphasis is laid on the fact that traces of late Classical astral mythologisation and deification are also recognisable in the Slovenian folk tradition. The relief, which is carved into a damaged plate of white limestone of irregular dimensions (124 x 70 cm) and inserted into the southern facade of the parish church of St George in Keutschach (Hodiše) in Austrian Carinthia, has long awaited a convincing expert interpretation.1 The relief depicts a mysterious anthropomorphic being with a halo, with a cross in place of the head and arms raised. Dr Emilijan Cevc, member of the Slovene Academy of Sciences and Arts, writes that this “seemingly mediocre though highly significant art monument […] at least to a certain extent sheds light on spiritual life in the earliest stages of Slovenian history […]”.2 Dr Vlado Nartnik, who drew a comparison between the Slovenian folk tradition and astronomical premises, was the first to indicate a connection between the Keutschach relief and the Orion constellation.3 I agree with both authors that the Keutschach relief has a symbolic, spiritual, mythological or religious meaning. Starting from different directions, they both drew close to the truth. But Cevc did not grasp the true content of the image since he was convinced that it depicted Christ in prayer, while Nartnik failed to give a more detailed explanation as to why Orion had been so important that the artist depicted it on a rock. My argument is based on three foundations: the context of the historical period and the geographical area; the interpretation of iconographic components; and certain ethnological parallels.…
