Question

Neoprene is What is the minimum bending radius of 1/2-inch medium-pressure flexible hose? Which one of the following types of fluid lines would be colour-coded with blue and yellow tape or decals? The recommended spacing distance between supports for 1/4-inch rigid tubing is Which one of the following metals will become corroded if it's placed in galvanic contact with other metals? The principle of eddy current inspection is based on how readily a material Microbial growth is a particular problem in or on Silicon carbide abrasive should not be used on

Explanation / Answer

4Q:-answer is c (a form of synthetic rubber)

explination:-Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Neoprene is sold either as solid rubber or inlatex form, and is used in a wide variety of applications, such as laptop sleeves, orthopedic braces (wrist, knee, etc.),

5Q:-answer is C (5 3/4 inches)

6Q:-ans is c(hydraulic lines)

explination:-Identification and colour coding for the pipelines is essential to avoid potential hazards, accidents. Giving a colour code and maintaining the uniformity for colour coding in industrial piping will eliminate accidental chances, reduces operational errors. Moreover it enhances the safety aspects.

blue is used to show the fluid that is not restricted,indicating there is minimal fluid pressure

yellow illustrates the controlled fluid flow after it passes to restricted valve

6Q:-ans is c ( 16 inches)

8Q:-answer is b(zinc)

explination:-If you couple zinc with stainless steel near the sea, you can get embrittlement of the stainless steel. This is due to the formation of atomic hydrogen when seawater breaks down and releases chlorine molecules.
As zinc is amphoteric it can be attacked by either very low or very high pH solutions. The hydrogen gas that forms can enter the molecular matrix of the stainless steel and expand, causing the steel to crack.

9Q:-answer is a(can be magnetised)

explination:-Alternating current running through a coil creates a magnetic field in and around the coil that is building and collapsing as the current changes. As current increases, the coil becomes more magnetic and induces circulating (eddy) currents in conductive material that is near the coil. The amplitude and phase of the eddy currents will change the loading of the coil and its impedance.

10Q:-answer is d(fuel tank)

explination:-Microbial colonies can proliferate in any fuel tank. All they need is food (fuel) and water to grow. Warm weather and the presence of biofuels will accelerate this process. Once these microbes have gained a foothold in your fuel tank, they can be hard to eliminate. The first step, of course, is to diagnose the problem and its severity.

11 Q:-answer is c (Magnesium alloys)
