To determine the minimum allowable overlap for a single-lap sheet splice using a double row of 1/8-inch rivets to repair damaged aluminum skin, additional information is needed to calculate the specific overlap length.

The minimum allowable overlap for a single-lap sheet splice depends on various factors such as the material strength, rivet size, and required strength of the splice joint. Without specific information about these factors, it is not possible to provide a precise answer for the minimum allowable overlap.
In general, the overlap length in a single-lap sheet splice should be sufficient to ensure proper load transfer and structural integrity. Factors to consider include the tensile strength of the material, the shear strength of the rivets, and the required strength of the splice joint. Engineering design guidelines and specifications, such as those provided by aircraft manufacturers or structural design codes, should be consulted to determine the appropriate overlap length for a given situation.

A stationary shock wave is one in which the flow field behind the shock is fixed in space. The stationary normal shock wave is a constant strength shock wave that is perpendicular to the direction of flow.

The downstream Mach number is a function of the upstream Mach number in a normal shock. The upstream Mach number is compared to a critical Mach number. The critical Mach number is the Mach number of the flow at a specific point in the flow, where the local velocity of the flow reaches Mach 1. When the upstream Mach number is less than the critical Mach number, there is no shock wave. When the upstream Mach number is greater than the critical Mach number, the flow is supersonic, and the shock wave exists.

Therefore, when the upstream Mach number increases toward infinity, the downstream Mach number of a stationary normal shock wave approaches an asymptotic minimum value. The asymptotic minimum Mach number for a gas with a specific heat ratio of 1.67 is 0.4. The upstream Mach number is related to the downstream Mach number via the following equation:\($$\frac{M_2}{M_1}=\sqrt{\frac{1+\frac{\gamma-1}{2}M_1^2}{\gamma M_1^2-\frac{\gamma-1}{2}}}$$\)Where:M1 is the upstream Mach number, M2 is the downstream Mach number, and γ is the ratio of specific heats. When γ = 1.67, the asymptotic minimum downstream Mach number is 0.4.

b) = U1 = 214.07

c) = V₁  = 0.861 m³/kg

d) = Vr1 = 621.2

Explanation:

Given that

R = 0.287 KJ/kg.K, T1 = 300 K , P1 = 100 kPa , V1 = 500 cm³, r = 10 , Q = 60 kW , Speed N = 5600 RPM, Number of cylinders K = 4

specific heat at constant volume Cv = 0.7174 kJ/kg.K

Specific heat at constant pressure is 1.0045 Kj/kg.K

a)  To determine the total mass (kg) of air in the engine.

we say

P1V1 = mRT1

we the figures substitute

(100 x 10³) ( 500 x  10⁻⁶) = m ( 0.287 x  10³) ( 300 )

50 = m x 86100

m = 0.00005 / 86100 = 0.0005807 ( mass of one cylinder)

Total mass of 4 cylinder

Mt = m x k

Mt = 0.0005807 x 4

A minimum set of requirements for plumbing installations in a municipality, city, county, or state is a plumbing code.

A plumbing code is a set of minimum standards and regulations that dictate the design, installation, and maintenance of plumbing systems. The code is typically enforced by local or state authorities and serves to protect public health and safety by ensuring that plumbing systems are safe, functional, and sanitary. Plumbing codes cover a wide range of requirements, including the size and type of pipes and fittings, fixture installation and location, drainage and venting, water supply, and backflow prevention. Plumbing codes are updated periodically to reflect advances in technology, changes in building materials, and new safety and environmental concerns. Compliance with the plumbing code is mandatory, and failure to meet the code requirements can result in fines, penalties, or legal action.

Answer:

A) V(t) = 0.4e^-2t

B) i(t) = (25tsin5t+10) A for t>0

Explanation:

Formula for calculating voltage across an inductor is expressed as:

V = Ldi/dt

Given L = 100mH = 100×10^-3

If i(t) = 6 - 2e^-2t A t >= 0

di/dt = (-2)(-2)e^-2t

di/dt = 4e^-2t

If t ≥ 0

V(t) = 100×10^-3 × (4e^-2t)

V(t) = 0.1×4e^-2t

V(t) = 0.4e^-2t for t≥0

B) Applying the same formula as above

V = Ldi/dt

Vdt = Ldi

V/L dt = di

On integration

Vt/L = i + C

When t = 0, i = -10A

Substituting the values into the formula

V(0)/L = -10 + C

0 = -10+C

C = 10

To get the current i(t) through the inductor for t>0,

Since Vt/L = i + C

Given V(t) = 5sin5t Volts

L = 200mH = 200×10^-3H

C = 10

On substituting

(5sin5t)t/0.2 = i + 10

25tsin5t = i + 10

i(t) = (25tsin5t-10) A for t>0

Answer:

Hydrostatic force = 41168 N

Explanation:

Complete question

A triangular plate with a base 5 ft and altitude 3 ft is submerged vertically in water  so that the top is 4 ft below the surface. If the base is in the surface of water, find the force against onr side of the plate. Express the hydrostatic force against one side of the plate as an integral and evaluate it. (Recall that the weight density of water is 62.5 lb/ft3.)

Let "x" be the side length submerged in water.

Then

w(x)/base = (4+3-x)/altitude

w(x)/5 = (4+3-x)/3

w(x) = 5* (7-x)/3

Hydrostatic force = 62.5 integration of  x * 4 * (10-x)/3 with limits from 4 to 7

HF = integration of 40x - 4x^2/3

HF = 20x^2 - 4x^3/9 with limit 4 to 7

HF = (20*7^2 - 4*7^(3/9))- (20*4^2 - 4*4^(3/9))

HF = 658.69 N *62.5 = 41168 N

By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3

The rate of flow (Q) will increase, as per the formula Q = -K  ˣ A  ˣ (Δh/ΔL) where K and (Δh/ΔL) are increasing, leading to an increased product (K  ˣ  (Δh/ΔL)) and hence, an increased rate of flow.

According to Darcy's Law, if the hydraulic gradient becomes steeper and the conductivity increases, the rate of flow will also increase.

Darcy's Law is defined as: Q = -K  ˣ A  ˣ (Δh/ΔL), where:

Q = rate of flow
K = hydraulic conductivity
A = cross-sectional area of flow
Δh = change in head (or hydraulic head difference)
ΔL = distance between the two points

The hydraulic gradient (Δh/ΔL) represents the slope of the hydraulic head or the driving force for fluid flow. When the hydraulic gradient becomes steeper, the value of (Δh/ΔL) increases.

Additionally, when the conductivity (K) increases, it means the porous medium allows fluid to flow more easily.

Since both the hydraulic gradient and conductivity are increasing, their product (K ˣ (Δh/ΔL)) will also increase, leading to an increased rate of flow (Q) according to Darcy's Law.

The correct answer of the question is the vertical displacement of joint b due to all effects is 0.75 in.

In physics, work is defined as the amount of energy transferred when a force is applied to an object and the object moves a certain distance in the direction of the force.

In other words, work is the product of the force applied and the displacement of the object in the direction of the force.

we can follow these steps.

Given:

Let's assume A = 1 in^2.

Assume a small vertical displacement at joint b, δb = 1 in.

δah = δav * (L1 / L2) = 0.75 * (8 / 10) = 0.6 in

where L1 is the horizontal distance between joint b and support a, and L2 is the total length of the truss.

W = F * δah = 20 * 0.6 = 12 kip-in

R = F * (L1 / L2) = 20 * (8 / 10) = 16 kip

Work done by R = R * δb = 16 * 1 = 16 kip-in

W = Work done by R

12 = 16 * δb

δb = 0.75 in

Therefore, the vertical displacement of joint b due to all effects is 0.75 in.
