Engineering
1 answer:
Naddika [18.5K]3 years ago
3 0

Answer Explanation:

SPRING STIFFNESS :The stiffness of a body is a measure of resistance offered by an elastic body to deformation.it is denoted by K every object has some stiffness for spring the spring stiffness is the force required to cause unit deflection

DAMPING CONSTANT: the damping constant is a number decided by manufacturer that describes the material property. Damping is an influence within an oscillatory system that has the effect of restricting its oscillation

6. Construct a neural network that computes the XOR function of two inputs. Make sure to specify what sort of units you are usin
IgorC [24]

Answer:

Figure 1 shows the neural network that computes the XOR of two inputs.

Two Input unit: X₁ and X₂

One hidden layer with two hidden units: h₁ and h₂

Two Weights for hidden unit 1 = 20, 20

Bias for hidden unit 1 = -10

Two Weights for hidden unit 2 = -20, -20

Bias for hidden unit 2 = 30

Weights for output layer = 20, 20

Bias for output layer = -30

Activation function = sigmoid (σ)

Output at hidden unit and at the output unit Y is shown in Table attached in Fig 2

These waveforms are applied to a gated D latch, which is initially RESET. Which of the areas identified on the Q waveform is inc
Andrej [43]

Question Completion with Options:

A) Area a B) Area b C) Area c D) Area d

Answer:

The incorrect waveform identified on the Q waveform is the:

C) Area c.

Explanation:

Area c is the incorrect waveform because its output is not correct.  The Q waveform indicates that the electrical forces project toward the negative pole of the lead axis.  A gated D latch is a flip flop latch with an additional control input, which determines when to change the state of the circuit. Most times, this control unit is a clock input or an enable input.

A sheet of steel 2.5 mm thick has nitrogen atmosphere on both sides at 900 oC and is permitted to achieve a steady-state diffusi
DanielleElmas [232]

Answer:

1.8 mm

Explanation:

given data

thick = 2.5 mm

flux = 1 × 10^{-7} kg/m²

high pressure surface is 2 kg/m³

solution

we use fick first law for steady state diffusion

J = D × \frac{Ca - Cb}{Xa - Xb}   ..........1

we take here Ca to point which concentration of nitrogen is 2 kg/m³

so we solve Xb

Xb = Xa + D × \frac{Ca - Cb}{J}

assume Xa = 0 at surface

Xb = 0 + ( 12 × 10^{-11} ) × \frac{2 - 0.5}{1*10^{-7}}

Xb = 1.8 × 10^{-3}

Xb = 1.8 mm
