How many times longer than the time constant tau is safe to assume dynamics completed?

(assuming this is talking about order systems...)

How will you decide a particular CNC machine for a particular operation ?

A person cuts a piece of Bronze that is 5" long with a 2.5" diameter down to 2.100 Dia.

It is done in 2 roughing passes and 1 finishing pass.

First pass from 2.5" to 2.3"

Second Pass from 2.3" to 2.110"

Third pass from 2.110" to 2.100"

What is the machine cutting time (in seconds)?

CS= 110 fpm for roughing and 140 fpm for finishing

Feed = .02 "/rev for roughing and .01"/rev for finishing

For the harmonic oscillator, briefly describe how the eigenvalues relate to the system being under-, critically-, or over-damped? Draw a sketch that relates the time course of solutions to the eigenvalues.

Technician A says that oil pan gaskets are often made of cork due to its ability to conform to small imperfections in the oil pan. Technician B says oil pan and valve cover gaskets are often MLS gaskets to account for the different expansion rates between components. Who is correct? a. Tec A b. Tec B c. Both A and b d. Neither A nor b.

Though the electric-gasoline engine allows better miles per gallon relative to a traditional gasoline engine, it is not without technological tradeoffs. Regarding the first electric-gasoline cars to market, much of the mpg achieved was due to styling not the ability to run on electricity, which from market surveys not as appealing as the styling of a sleeker vehicle body design. New and limited infrastructure for servicing these vehicles was created, which may have deterred buyer acceptance.

Question

What fundamental technical constraints are added when incorporating an electric-gas engine into a vehicle design?

Is the inventive concept itself diluted or enhanced by the embodiment required, especially in regards to vehicle styling?

What new business operations are needed to support the new engine design?

What will drive both acceptance and sales of this new type of vehicle?

Compare the technical constraints of the electric-gasoline engine to the conventional gasoline engine.

can you apply real gas equation to a saturated liquid state or super heated state??

In a three-point balancing test without phase the values for the original vibrations are V0=10 mm, and the values of the amplitude of vibration for the three points in the test with a trial mass, mt, of 50 g are:
V1=14 mm at 0 degrees
V2=20 mm at 120 degrees
V3=7 mm at 240 degrees

A heat engine operates by extracting 2,000 KJ of heat from a source at 1500 K, and dumping 800 of waste heat into a sink at 300 K. a) Does this engine violate any known laws of thermodynamics? b) How much work does this engine produce? c) What are the first and second law efficiencies?
