In a bipolar junction transistor, the current gain can be defined as the ratio of the collector current to the base current. It is generally denoted by \(hFE\)or \(β\).

When collector current (IC) is 10 mA and base current (IB) is 0.1 mA, then the current gain is given by the ratio of collector current to base current.

Therefore, the current gain (\(β\)) is given as:

\(β = IC/IBβ = 10/0.1β = 100\)

Thus, the current gain of the transistor is 100. This indicates that for every 1 mA of base current, the collector current is 100 mA. It is important to note that the current gain is not constant and varies with temperature, current, and other factors.

The current gain is an important parameter in transistor amplifiers as it determines the amplification factor of the circuit. An increase in the current gain leads to higher amplification and vice versa.

It is essential to choose a transistor with the appropriate current gain for a given application to ensure optimal performance.

Answer:

E = 8.83 kips

Explanation:

First, we determine the stress on the rod:

\(\sigma = \frac{F}{A}\\\\\)

where,

σ = stress = ?

F = Force Applied = 1300 lb

A = Cross-sectional Area of rod = 0.5\(\pi \frac{d^2}{4} = \pi \frac{(0.5\ in)^2}{4} = 0.1963\ in^2\)

Therefore,

\(\sigma = \frac{1300\ lb}{0.1963\ in^2} \\\\\sigma = 6.62\ kips\)

Now, we determine the strain:

\(strain = \epsilon = \frac{elongation}{original\ length} \\\\\epsilon = \frac{0.009\ in}{12\ in}\\\\\epsilon = 7.5\ x\ 10^{-4}\)

Now, the modulus of elasticity (E) is given as:

\(E = \frac{\sigma}{\epsilon}\\\\E = \frac{6.62\ kips}{7.5\ x\ 10^{-4}}\)

E = 8.83 kips

a. 0.10

2. If the marginal propensity to consume (MPC) is 0.9, a $100 increase in government spending, other things being equal, will cause an increase of real GDP of:
c. $900

3. If the marginal propensity to consume (MPC) is 0.9, the value of the tax multiplier is:
d. -9

1. If the marginal propensity to consume (MPC) is 0.9, the marginal propensity to save (MPS) is determined by the following steps :
The sum of MPC and MPS always equals 1.

Therefore, if MPC is 0.9,

MPS = 1 - 0.9 = 0.10.

2. If the marginal propensity to consume (MPC) is 0.9, to determine the increase of real GDP follow the given steps :
The spending multiplier is 1 / (1 - MPC).

In this case, the spending multiplier is 1 / (1 - 0.9) = 10.

So, a $100 increase in government spending will result in a $100 x 10 = $900 increase in real GDP.

3. If the marginal propensity to consume (MPC) is 0.9, the value of the tax multiplier is determined by the following steps:

As a project manager, I would employ the following strategy to address resistance to changes in the home renovation project:

Strategy: Effective Communication and Stakeholder Engagement

To address resistance to changes, it is crucial to establish open and transparent communication channels with all stakeholders involved in the project. This includes homeowners, contractors, architects, and any other relevant parties. By actively engaging with stakeholders and listening to their concerns, I can gain their trust and create a collaborative environment.

Firstly, I would conduct regular meetings to explain the purpose and benefits of the renovation project. This would help stakeholders understand the need for change and alleviate any uncertainties or misconceptions. Clear and concise communication is key to ensuring everyone is on the same page.

Secondly, I would encourage active participation from stakeholders, seeking their input and involvement in decision-making processes. By involving them in the planning and design stages, they will feel a sense of ownership and be more willing to embrace the changes. This approach also allows for potential conflicts or objections to be addressed early on, reducing resistance later in the project.

Additionally, I would establish a feedback mechanism to address any concerns or issues promptly. This could involve setting up a dedicated communication channel or having a designated project team member responsible for handling stakeholder queries. Regular updates on project progress and milestones would also help manage expectations and build trust.

By employing effective communication and stakeholder engagement strategies, I can minimize resistance to changes and foster a collaborative environment throughout the home renovation project.

2.1) The support reactions are calculated now: \(A_{x} = 10\,kN\), \(A_{y} = -10\,kN\), \(B_{y} = 30\,kN\).

2.2) The member CD is on tensile load and the member BC is on compressive load. \(F_{BC} \approx 28.284\,kN\), \(F_{CD} = 20\,kN\)

The dynamic situation of a mechanical system whose geometry cannot be neglected is described by Newton's laws and D'Alembert's principle. A planar system in equilibrium is described by the following formulae:

\(\sum F_{x} = 0\)     (1)

\(\sum F_{y} = 0\)     (2)

\(\sum M = 0\)     (3)

2.1) The support reactions can be found by assuming that the truss is a rigid solid:

\(\sum F_{x} = A_{x} - F = 0\)    (4)

\(A_{x} = F\)

\(A_{x} = 10\,kN\)

\(\sum M_{A} = F\cdot r_{BD} - G \cdot (r_{AB}+r_{CD}) + B_{y}\cdot r_{AB} = 0\)     (5)

\(B_{y} = \frac{G\cdot (r_{AB}+r_{CD})-F\cdot r_{BD}}{r_{AB}}\)

\(B_{y} =\frac{(20\,kN)\cdot (8\,m)-(10\,kN)\cdot (4\,m)}{4 \,m}\)

\(B_{y} = 30\,kN\)

\(\sum F_{y} = A_{y} + B_{y} - G = 0\)     (6)

\(A_{y} = G - B_{y}\)

\(A_{y} = 20\,kN - 30\,kN\)

\(A_{y} = -10\,kN\)

Note - The negative sign means that the real direction of the component is antiparallel to the assumed one.

2.2) If the entire system is at equilibrium, then every part of the system must be also at equilibrium. The joint is considered a particle and thus the D'Alembert's principle is not necessary. The member CD is on tensile load and the member BC is on compressive load.

\(\sum F_{x} = F_{BC} \cdot \cos 45^{\circ} - F_{CD} = 0\)     (7)

\(\sum F_{y} = -G + F_{BC}\cdot \sin 45^{\circ} = 0\)     (8)

By (8):

\(F_{BC} = \frac{G}{\sin 45^{\circ}}\)

\(F_{BC} \approx 28.284\,kN\)

We can conclude that f(n) ∈ O(g(n)), which means that the order of growth of f(n) is at most the same as the order of growth of g(n).

For the given pair of functions f(n) and g(n), we have f(n) ∈ O(g(n)).

Explanation:

First, let's define the three notations mentioned in the question:

- Θ(g(n)) represents a set of functions with the same order of growth as g(n).
- O(g(n)) represents a set of functions with an order of growth that is at most the same as g(n).
- Ω(g(n)) represents a set of functions with an order of growth that is at least the same as g(n).

Now, let's analyze the given functions:

f(n) = 3 × n!
g(n) = (3 × n)!

We can see that the order of growth of g(n) is much larger than the order of growth of f(n). This is because the factorial of a larger number will always be greater than the factorial of a smaller number. In this case, (3 × n)! will always be greater than 3 × n!.
