Various machine components used in mechanical engineering. Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [1]
The University of KwaZulu-Natal (UKZN; Zulu: INyuvesi yakwaZulu-Natali, Afrikaans: Universiteit van KwaZulu-Natal) is a public research university with five campuses in the province of KwaZulu-Natal in South Africa. [7] [6] It was formed on 1 January 2004 after the merger between the University of Natal and the University of Durban-Westville. [1]
In 1974 the Chief Minister of KwaZulu, Dr Mangosuthu Buthelezi, began discussing the idea of a dedicated tertiary educational institution specialising in technical subjects for black students, to meet the urgent and growing demand for expertise in these subjects.
Many PID loops control a mechanical device (for example, a valve). Mechanical maintenance can be a major cost and wear leads to control degradation in the form of either stiction or backlash in the mechanical response to an input signal. The rate of mechanical wear is mainly a function of how often a device is activated to make a change.
Engineering problems are generally tackled with applied mechanics through the application of theories of classical mechanics and fluid mechanics. [4] Because applied mechanics can be applied in engineering disciplines like civil engineering, mechanical engineering, aerospace engineering, materials engineering, and biomedical engineering, it is sometimes referred to as engineering mechanics.
An order from the engineering department (to be followed by the production department or vendor) overriding/superseding a detail on the drawing, which gets superseded with revised information. Also called by various other names, such as engineering change order (ECO), engineering change notice (ECN), drawing change notice (DCN), and so on.
The module is the measure of gear tooth size which is normally used for metric system gears. It is similar to the Diametral Pitch (DP), which is commonly used for UK system (inch measure) gears but they differ in the units used and in that they bear a reciprocal relationship. Module is the pitch circle diameter divided by the number of teeth.
Under apartheid, the Howard College Campus, in Durban, was known for the activism of its staff and students against government-imposed racial segregation. Particularly in the 1960s Natal University students were active in the non-racial National Union of South African Students, which was one of the main organizations opposing the apartheid system.
