A structural design project may be divided into three phases, i.e. planning, design and construction. Planning: This phase involves consideration of the various requirements and factors affecting the general layout and dimensions of the structure and results in the choice of one or perhaps several alternative types of structure, which

The Hipot Test (Dielectric Voltage Withstand) The Hipot test is the most common type of safety test. This test is designed to stress a product’s insulation beyond what it would encounter during normal use. The reasoning behind this test is that if the insulation can withstand high voltage for short
There are several types of the electronic circuitry used within battery chargers for the marine market. FERRO-RESONANT (or CVT) These use a low-frequency MAGNETIC control system, which makes them very HEAVY, very BULKY and is also only available with a poor FLOAT charge characteristic, therefore very SLOW recharging. They can
The LC and RC oscillators have their own limitations. The major problem in such circuits is that their operating frequency does not remain strictly constant. There are two principal reasons for it viz., As the circuit operates, it will warm up. Consequently, the values of resistors and inductors, which are
An electronic device that generates sinusoidal oscillations of desired frequency is known as a sinusoidal oscillator. Oscillator does not create energy, but merely acts as an energy converter. It receives DC energy and changes it into AC energy of desired frequency. The frequency of oscillations depends upon the constants of
A weld joint refers to how the parts to be joined are assembled prior to welding. There are five basic types of joints used in welding which are Butt, Lap, Corner, T & Edge. The metal to be joined is called the base metal. If the part to be welded
