Q.1 The inductance of moving iron ammeter in micro henry is given by expression: L=20+5?-2?2 Where ? is deflection in radians from the zero position. Determine the angular in radians for a current of 10A if the for a current of 5A is 300.Also determine the spring constant. Q.2 .For a certain electrodynamometer ammeter the mutual inductance M varies with the deflection of ? as M=-6cos(?+300)mH Find the deflecting torque produced by the direct current of 50mA corresponding to the deflection of 600. Q.3 . A 220V,10A dc energy meter is tested at its marked ratings. The resistance of pressure coil is 9900ohm and that of current coil is 0.5ohm .Calculate the power consumed when testing the meter with (i).Direct loading arrangements (ii).Phantom loading with current circuit excited by a 6V battery Q.4. Power in a dc circuit is calculated as the product of current and voltage if the value of current and voltage are given by 6.3A and 110.2V and the uncertainties.....

Risk assessment


Practical Exercise: 1 (40 marks) Subject Risk assessment exercise on a typical long distance conveyer for transporting newly mined coal away from the coal face Objective To gain basic experience with the risk assessment and risk reduction procedures as described in chapter 3 of the course manual and as required by EN ISO 14121 and AS 4024.1301 Relevance All machinery safety projects should be subjected to this type of procedure. Provides a simple practice routine. This example is typical and it makes use of: A. Hazards checklist from both of the above standards. B. The risk scoring system advocated by PILZ and by Proctor machine Guarding. C. An Excel spreadsheet format based on the software tool issued by Proctor and demonstrated during the training course. Starting Information: Suppose you are the designer for an underground conveyor installation that is to transport raw coal in lumped and crushed forms and all debris from a coal cutting area over a distance of more than 1000.....

Assignment Final Week


Question 1: A contemporary issue facing technology innovation today is the tension between personal privacy and public security. Discuss in-depth how this issue effects and drives the development of devices or software. Provide at least one example. (Write at least 2 - 3 paragraphs) Question 2: Consider the following case study and answer the questions below. An electric car is an automobile that uses electrical energy stored in batteries or another energy storage device that is propelled by one or more electric motors. Electric cars can significantly reduce air pollution, as they do not emit tailpipe pollutants and reduce in greenhouse gas and other emissions and reduce dependence on foreign oil. But widespread adoption of electric cars causes higher cost, lack of recharging infrastructure outside of home charging and range anxiety which is the driver's fear that the electric energy stored in the batteries will run out before the driver reaches.....
