Answer:
social regulation.
Explanation:
Social regulation are rules set aside to protect the environment or restrain activities that poses threat to public health and safety, examples includes environment pollution which includes lands, air, water etc, unhealthy work environment, etc. This rules identify activities that are allowed or under sanction for individuals, firms and government, breaking this rules most times comes with heavy fines or sanctions.
Social regulation help to see to the safety and well being of our environment, it serves as a guide for human activities.
Answer:
The answer is option
C . the JFET has a PN junction
Explanation:
Not only is option C in the question a dissimilarity between the MOSFET and the JFET we can go on with some more dissimilarities.
1.MOSFET stands for Metal Oxide Silicon Field Effect Transistor or Metal Oxide Semiconductor Field Effect Transistor.
(JFET) stands for junction gate field-effect transistor (JFET)
2. JFET is a three-terminal semiconductor device, whereas MOFET a four-terminal semiconductor device.
3. In terms of areas of application of JFETs are used in low noise applications while MOSFETs, are used for high noise applications
Answer:
small guitar with no strings?
Explanation:
it would be fun to make i think
Answer:
Part a: The yield moment is 400 k.in.
Part b: The strain is ![8.621 \times 10^{-4} in/in](https://tex.z-dn.net/?f=8.621%20%5Ctimes%2010%5E%7B-4%7D%20in%2Fin)
Part c: The plastic moment is 600 ksi.
Explanation:
Part a:
As per bending equation
![\frac{M}{I}=\frac{F}{y}](https://tex.z-dn.net/?f=%5Cfrac%7BM%7D%7BI%7D%3D%5Cfrac%7BF%7D%7By%7D)
Here
- M is the moment which is to be calculated
- I is the moment of inertia given as
![I=\frac{bd^3}{12}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7Bbd%5E3%7D%7B12%7D)
Here
- b is the breath given as 0.75"
- d is the depth which is given as 8"
![I=\frac{bd^3}{12}\\I=\frac{0.75\times 8^3}{12}\\I=32 in^4](https://tex.z-dn.net/?f=I%3D%5Cfrac%7Bbd%5E3%7D%7B12%7D%5C%5CI%3D%5Cfrac%7B0.75%5Ctimes%208%5E3%7D%7B12%7D%5C%5CI%3D32%20in%5E4)
![y=\frac{d}{2}\\y=\frac{8}{2}\\y=4"\\](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bd%7D%7B2%7D%5C%5Cy%3D%5Cfrac%7B8%7D%7B2%7D%5C%5Cy%3D4%22%5C%5C)
![\frac{M_y}{I}=\frac{F_y}{y}\\M_y=\frac{F_y}{y}{I}\\M_y=\frac{50}{4}{32}\\M_y=400 k. in](https://tex.z-dn.net/?f=%5Cfrac%7BM_y%7D%7BI%7D%3D%5Cfrac%7BF_y%7D%7By%7D%5C%5CM_y%3D%5Cfrac%7BF_y%7D%7By%7D%7BI%7D%5C%5CM_y%3D%5Cfrac%7B50%7D%7B4%7D%7B32%7D%5C%5CM_y%3D400%20k.%20in)
The yield moment is 400 k.in.
Part b:
The strain is given as
![Strain=\frac{Stress}{Elastic Modulus}](https://tex.z-dn.net/?f=Strain%3D%5Cfrac%7BStress%7D%7BElastic%20Modulus%7D)
The stress at the station 2" down from the top is estimated by ratio of triangles as
![F_{2"}=\frac{F_y}{y}\times 2"\\F_{2"}=\frac{50 ksi}{4"}\times 2"\\F_{2"}=25 ksi](https://tex.z-dn.net/?f=F_%7B2%22%7D%3D%5Cfrac%7BF_y%7D%7By%7D%5Ctimes%202%22%5C%5CF_%7B2%22%7D%3D%5Cfrac%7B50%20ksi%7D%7B4%22%7D%5Ctimes%202%22%5C%5CF_%7B2%22%7D%3D25%20ksi)
Now the steel has the elastic modulus of E=29000 ksi
![Strain=\frac{Stress}{Elastic Modulus}\\Strain=\frac{F_{2"}}{E}\\Strain=\frac{25}{29000}\\Strain=8.621 \times 10^{-4} in/in](https://tex.z-dn.net/?f=Strain%3D%5Cfrac%7BStress%7D%7BElastic%20Modulus%7D%5C%5CStrain%3D%5Cfrac%7BF_%7B2%22%7D%7D%7BE%7D%5C%5CStrain%3D%5Cfrac%7B25%7D%7B29000%7D%5C%5CStrain%3D8.621%20%5Ctimes%2010%5E%7B-4%7D%20in%2Fin)
So the strain is ![8.621 \times 10^{-4} in/in](https://tex.z-dn.net/?f=8.621%20%5Ctimes%2010%5E%7B-4%7D%20in%2Fin)
Part c:
For a rectangular shape the shape factor is given as 1.5.
Now the plastic moment is given as
![shape\, factor=\frac{Plastic\, Moment}{Yield\, Moment}\\{Plastic\, Moment}=shape\, factor\times {Yield\, Moment}\\{Plastic\, Moment}=1.5\times400 ksi\\{Plastic\, Moment}=600 ksi](https://tex.z-dn.net/?f=shape%5C%2C%20factor%3D%5Cfrac%7BPlastic%5C%2C%20Moment%7D%7BYield%5C%2C%20Moment%7D%5C%5C%7BPlastic%5C%2C%20Moment%7D%3Dshape%5C%2C%20factor%5Ctimes%20%7BYield%5C%2C%20Moment%7D%5C%5C%7BPlastic%5C%2C%20Moment%7D%3D1.5%5Ctimes400%20ksi%5C%5C%7BPlastic%5C%2C%20Moment%7D%3D600%20ksi)
The plastic moment is 600 ksi.
