ISOBARIC PROCESS / ISOMETRIC PROCESS   answer subpart D and E thank you so much!!

(Subject: Instrumentation & Measurements) Hello dear, I now have a very important test, and I need to answer in a short time, less than an hour And if you give me the answer within the specified time, I will like you on your answer and invite my colleagues also and thank you.

Answer the following question: 1. What are the the things that needs to be checked when performing an on-aircraft inspection?

Functional testing check sheet for Lithotripsy machine, self-illuminating microscope and Holmium laser.

Which one of the below statements is mostly NOT correct about in creation of detailed design of component? The selection of material is based on what is required to performance the function. The tolerance is determined by the function, not the preference of designer or manufacture. In the selection of manufacturing processes, the number of components to be manufactured needs to be considered, as the capital investment needs to be considered. I do not need to show or prove the component is working: such how much electricity is generated in power panel, how much braking force is generated in by the brake disc, or how much the force the component in suspension is subjected?

What are the type of aircraft propeller shop inspection? Define each

True or False? Common way of classifying mechanical device is by function.  The goal during the design process is to learn as much about the evolving product as early as possible in the design process because during the early phases changes are least expensive.

1. What type of measurements are most often obtained when testing vehicle circuits ? 2. What measurement is common in testing audio system and many modern door lock system ?

True/False 1. ____ Metals have long and thin bubbles in Strength-Modulus Chart because the processes used to manipulate their properties have almost no effect on the modulus but have a dramatic effect on strength. 2. ____ Cross-linking, blending and filling of polymers with particulates or fibers do not change their modulus or strength. 3. ____ The strength of ceramics depends on porosity, generally the higher the porosity, the higher the strength. 4. ____ Three basic ways to manipulate the mechanical properties of metals are: solution hardening, precipitation hardening, and work hardening. 5. ____ Foaming reduces density of metals, ceramics, and polymers but does not affect modulus.

is a measure of internal resistance caused by electrical environment of the particles. a. Effective viscosity b. Apparent viscosity c. Plastic viscosity d. Yield point e. Both a and b

TRUE OR FALSE. concurrent engineering is used to compare material, design, fabrication, and quality to different kinds of product and parts.

A vehicle's Maximum Gross Weight (MGW) can be found on the New York State registration and is used to determine what type of safety inspection is done on a vehicle. True or False?

A datum when used in manufacturing is primarily used for?     Define the functional relationship to another feature on a part, or they have a functional relationship in an assembly. They are the origin from which many Geometric tolerances are measured.     Datums are used to describe how one part must fit or align to a mating part.     A datum should be placed on the smallest surface of the part to be sure that the mating part would fit.     Datums assure that parts will always fit together.
