While combing through the hair during a haircut service, the shears should be held at the appropriate angle based on the desired outcome and technique. Maintaining control, precision, and even tension is key for a successful haircut service.
During a haircut service, the shears should be held at a proper angle to achieve the desired outcome. It is essential to maintain control and precision when using shears, as they play a crucial role in the overall quality of the haircut. The angle of the shears will depend on the technique being used and the desired look. For instance, if you're aiming for a blunt cut, the shears should be held parallel to the hair section being cut. On the other hand, if you're looking to create texture or blend layers, you would hold the shears at a 45-degree angle or utilize point cutting techniques. Moreover, while combing through the hair, it is important to maintain even tension to ensure accuracy in the cut. Keeping the comb and shears in sync is vital to achieve a clean, precise haircut. Remember to use professional-grade shears and keep them sharp to ensure a smooth cutting experience and avoid damage to the hair.

A discrete MOSFET common-source amplifier has R = 2 MQ, gm=4 mA/V, r = 100 k2, R, = 10 k2, C=2 pF, and gs =0.5 pF. The amplifier is fed from a voltage source with an Ced gd internal resistance of 500 k2 and is connected to a 10-k load. Find:
(a) the overall midband gain AM
(b) the upper 3-dB frequency f
a. the upper 3-dB frequency (f) of the discrete MOSFET common-source amplifier is approximately 808.65 MHz. b. the midband gain (AM) of the discrete MOSFET common-source amplifier is approximately -3.88.
(a) To find the overall midband gain (AM) of the discrete MOSFET common-source amplifier, we can use the following formula:
AM = -gm * (R || r) * (Rd || RL)
where gm is the transconductance of the MOSFET, R is the resistance connected to the drain, r is the output resistance of the MOSFET, Rd is the internal resistance of the voltage source, and RL is the load resistance.
Given:
gm = 4 mA/V
R = 2 MΩ
r = 100 kΩ
Rd = 500 kΩ
RL = 10 kΩ
We can calculate the parallel combination of resistances (R || r) as follows:
(R || r) = (R * r) / (R + r)
Substituting the given values:
(R || r) = (2 MΩ * 100 kΩ) / (2 MΩ + 100 kΩ) = 98.039 kΩ
Next, we calculate the parallel combination of resistances (Rd || RL) as follows:
(Rd || RL) = (Rd * RL) / (Rd + RL)
Substituting the given values:
(Rd || RL) = (500 kΩ * 10 kΩ) / (500 kΩ + 10 kΩ) = 9.901 kΩ
Now, we can calculate the overall midband gain:
AM = -gm * (R || r) * (Rd || RL)
= -4 mA/V * 98.039 kΩ * 9.901 kΩ
≈ -3.88
Therefore, the overall midband gain (AM) of the discrete MOSFET common-source amplifier is approximately -3.88.
(b) The upper 3-dB frequency (f) can be calculated using the formula:
f = 1 / (2π * (R || r) * C)
where (R || r) is the parallel combination of resistances and C is the capacitance.
Given:
(R || r) = 98.039 kΩ
C = 2 pF
Substituting the given values:
f = 1 / (2π * 98.039 kΩ * 2 pF)
≈ 808.65 MHz
Therefore, the upper 3-dB frequency (f) of the discrete MOSFET common-source amplifier is approximately 808.65 MHz.

by what factor is the maximum shear stress greater than the average shear stress acting over the cross section?
The ratio of τmax and τavg is defined as the shear stress factor, and it has important implications in the design of materials and structures.
The shear stress factor can vary widely, depending on the material and the loading conditions, and it can be a critical factor in the failure of a material or structure. In general, the shear stress factor is higher for ductile materials than for brittle materials. This is because ductile materials can absorb more energy before they fail, which means that they can handle higher stresses without fracturing. Brittle materials, on the other hand, tend to fail suddenly and catastrophically when they reach their maximum stress, which means that they cannot handle high shear stresses for long.
In conclusion, the maximum shear stress is usually much greater than the average shear stress acting over the cross-section, and the ratio of the two is defined as the shear stress factor. The shear stress factor can vary widely depending on the material and the loading conditions, and it is an important factor to consider in the design of materials and structures. It can be a critical factor in the failure of a material or structure, and it is important to choose materials and designs that can handle high shear stresses without failing suddenly and catastrophically.

Answer:
a) 53 MPa, 14.87 degree
b) 60.5 MPa
Average shear = -7.5 MPa
Explanation:
Given
A = 45
B = -60
C = 30
a) stress P1 = (A+B)/2 + Sqrt ({(A-B)/2}^2 + C)
Substituting the given values, we get -
P1 = (45-60)/2 + Sqrt ({(45-(-60))/2}^2 + 30)
P1 = 53 MPa
Likewise P2 = (A+B)/2 - Sqrt ({(A-B)/2}^2 + C)
Substituting the given values, we get -
P1 = (45-60)/2 - Sqrt ({(45-(-60))/2}^2 + 30)
P1 = -68 MPa
Tan 2a = C/{(A-B)/2}
Tan 2a = 30/(45+60)/2
a = 14.87 degree
Principal stress
p1 = (45+60)/2 + (45-60)/2 cos 2a + 30 sin2a = 53 MPa
b) Shear stress in plane
Sqrt ({(45-(-60))/2}^2 + 30) = 60.5 MPa
Average = (45-(-60))/2 = -7.5 MPa
