Explanation:

A solid state laser contains a cavity like structure fitted with spherical mirrors or plane mirrors at the end filled with a rigidly bonded crystal. It uses solid as the medium. It uses glass or crystalline materials.

It is known that active medium used for this type of laser is a solid material. This lasers are pumped optically by means of a light source which is used as a source of energy for the laser. The solid materials gets excited by absorbing energy in the form of light from the light source. Here the pumping source is light energy.

The maximum gage pressure is known to be 10 MPa in a spherical steel pressure vessel having a 200 mm outer diameter and a(n) 2 m

VikaD [51]

Answer:

factor of safety = 0.8

Explanation:

given data

maximum gauge pressure in steel p = 10 MPa

outer diameter do = 200 mm

wall thickness t = 2 mm

ultimate stress of the steel σU = 400 MPa

solution

We check the type of shell that is

$\frac{t}{do} =\frac{6}{200}$

so we can see that that is

so that it mean vessel is a thin shell now we can we get maximum pressure by the maximum tensile stress is

σ = $\frac{p\times do}{2t}$ .......................1

put here value and we get

σ = $\frac{10\times 200}{2\times 2}$

σ = 500 MPa

so factor of safety will be express as

factor of safety = $\frac{\sigma U}{\sigma}$ ..........2

factor of safety = $\frac{400}{500}$

factor of safety = 0.8

As you recall, the Logic Schematic for Lab2&3 (‘Smart ECC Transportation ‘Bus’ with Robotic Arm: 4-Bit Microcomputer) was ve

Thepotemich [5.8K]

Answer:

Explanation:

In the first instance, you had a logic function, which you had derived using some sort of a truth table, then reduced it using K-maps, and finally derived the simplified logic. If you had used logic gates to implement the logic, the result would have been the fact that there were a lot of logic gates used. For example, for a function of 2 variables, we would need 4 AND gates and 1 OR gate. Thus, the resulting circuitry would have looked very complex.

Whereas, if you would use a microcontroller to implement the logic, all you need would be a piece of code to run the logic. There would either be minimum number of gates (or no gates at all, depending on the logic you wanted to implement).

Thus the microcontroller would make the circuit look a lot less complex. Making the design and texting simpler and since there are now fewer components to test. Microcontrollers is that on the same piece of silicon, you could embed a lot more complex logic or program, than using purely digital gates this is another good that comes with Microcontrollers.

marta [7]

Answer:

A periodic function is a function that returns to its value over a certain period at regular intervals an example is the wave form of flux density (B) = sin wt

Explanation:

A periodic function is a function that returns to its value over a certain period at regular intervals an example is the wave form of flux density (B) = sin wt

attached to the answer is a free plot of the output starting with zero degree for one coil rotating in a uniform magnetic field

B ( wave flux density ) = Bm sinwt and w = 2 $\pi$ f = $\frac{2\pi }{T}$ rad/sec
