1. Delta j under unit column are always zero. 2. Calculate z while doing row operations. 3 in regular simplex method, in initial table delta j are the negative of Cj. So there is no need to calculate...
Fluid Mechanics: An applied science Part AAbstractThis paper identifies fluid mechanics as an essential component of engineering and its applications in everyday life. The fundamental formula and equations...
Resistors are used for: – Limiting current in electric circuits. – Lowering voltage levels in electric circuits (using voltage divider). – As current provider. – As a sensor...
(i) Facing: This operation is almost essential for all works. In this operation, as shown in fig., the work piece is held in the chuck and the facing tool is fed from the center of the work piece towards...
An oscillator is a circuit that creates a waveform output from a direct current input. The two main types of oscillator are harmonic and relaxation. The harmonic oscillators have smooth curved waveforms,...
