HISTORY OF CUTTING TOOL MATERIALS • Cutting tool used during the industrial revolution in 1800 A.D • First cutting tool was cast using crucible method (1740) and slight hardened by H.T. • 1868: R. Mushet found by adding Tungsten we can increase hardness and tool life ( Air Quenching) • F.W.Taylor in Pennsylvania did the most basic research in metal cutting between 1880-1905 • Invented high speed steel (better H.T. process) • Better alloy

Q1 Q1 A) The sudden closure of valve at the end of a pipeline cause sudden change in the water velocity which in turn creates a phenomenon called water hammer. The water in motion is forced to stop or change direction suddenly (momentum change) and a pressure wave propagates in the pipe. It ’s also called hydraulic shock. The effect of this event can be effectively multiplied many times by the geometry of a piping system if the pressure wave is allowed to reflect‚ or bounce‚ back and forth

Within as little as a month‚ an entire population can be obliterated by deadly disease. This might have been the case in a district in London if not for the genius of a local anaesthesiologist who ended one of the most well-known outbreaks of cholera in history by using strategies epidemiologists use to this day. The year is 1854 in Soho‚ London where living conditions are abominable. Dense population‚ lack of waste management‚ and the dearth of knowledge concerning sickness all contribute to the

HYDRAULIC THEORY Introduction A hydraulic system is defined as a‚ ‘machinery unit which uses fluid as a pressure medium’. It has a number of advantages over an electrical system of a similar working capacity. Advantages: (1) The power to weight ratio is at least 14 times better than an equivalent electrical system. (2) Self-resetting overload protection. (3) Self-lubricating. (4) Infinitely variable speeds. (5) No static electricity. (6) Linear motion.

another. To understand this‚ resistance and contributing factors‚ such as vessel radius‚ viscosity‚ and vessel length must be studied. The effects of vessel radius and stroke volume on the ventricular pump should also examined. The experiment also calls for an understanding of cardiovascular compensation. Pump mechanics are further understood through a design of further experiments. The Cardiovascular Physiology experiment attempts to understand the effects of parasympathetic and sympathetic nervous systems
