Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

ETO Case Study Analysis Seligram Incorporation‚ Electric Testing Operations (ETO) previously measured two components of cost: direct labor and manufacturing overhead. The existing cost system is very simple. Burden was grouped into a single cost pool that was combined with each of the testing rooms as well as the engineering burden costs related to software and tooling development and the administrating costs of the department. The total burden costs was then divided by the sum of testing and

to the 555 timer circuit that was being used as a square wave oscillator to provide a clock pulse. When used in stable mode‚ the 555 acts as a square wave oscillator whose clock rate is dependent on a time constant provided by two resistors and a capacitor. Many of the 555s weren’t providing a stable clock

GASEOUS DISCHARGE LAMPS: A gaseous discharge lamp is essentially a glass or quartz envelop containing two electrodes and a small quantity of gas or vapour at a low pressure. In these lamps light is obtained by applying an electric potential difference to a gas or vapour contained by the lamp under a suitable pressure. Due to application of electric potential difference gas gets ionised and an electric current flows; the tube is filled with a luminous discharge. The light spectrum
