The location of the centre of pressure of a positive cambered wing at increasing angle of attack will shift forward. This is because the positive camber creates a convex surface on the top of the wing, which results in a higher pressure on the top surface compared to the bottom surface.
As the angle of attack increases, this pressure differential becomes more pronounced, causing the centre of pressure to move forward towards the leading edge of the wing.This forward shift in the centre of pressure can have important implications for aircraft stability and control. If the centre of pressure moves too far forward, the aircraft may become unstable and difficult to control. However, designers can adjust the wing's shape and size to optimize the location of the centre of pressure for a given aircraft design and operating conditions.Overall, understanding the behaviour of the centre of pressure is an important aspect of aerodynamics, as it can have a significant impact on the performance and safety of aircraft.For such more question on pronounced

Explanation:
Apply the particle under a net force model to the block in the horizontal direction:1) Fx = F cos θ - fk - T = m2ax = m2aApply the particle in equilibrium model to the block in the vertical direction:2) Fy = n + F sin θ - m2g = 0Apply the particle under a net force model to the ball in the vertical direction:3) Fy = T - m1g = m1ay = m1aSolve Equation (2) for n:n = m2g - F sin θSubstitute n into fk = ?kn from the above equation:4) fk = k (m2g - Fsin θ)Substitute Equation (4) and the value of T from Equation (3) into Equation (1):F cos θ - k(m2g - Fsin θ) - m1(a + g) = m2aSolve for a in terms of k, m1, m2, g, and ?:
Answer:
[F cos θ - k(m2g - Fsin θ) + m1g]/(m1 + m2)
Explanation:
Since F cos θ - k(m2g - Fsin θ) - m1(a + g) = m2a
Expanding the bracket containing a, we have
F cos θ - k(m2g - Fsin θ) - m1a + m1g = m2a
Collecting the terms in a to the right-hand-side of the equation, we have
F cos θ - k(m2g - Fsin θ) + m1g = m1a + m2a
Factorizing a out, we have
F cos θ - k(m2g - Fsin θ) + m1g = (m1 + m2)a
Dividing both sides by (m1 + m2), we have
[F cos θ - k(m2g - Fsin θ) + m1g]/(m1 + m2) = a
So, a = [F cos θ - k(m2g - Fsin θ) + m1g]/(m1 + m2)

A cylindrical specimen of a hypothetical metal alloy is stressed in compression. If its original and final diameters are 20.000 and 20.025 mm, respectively, and its final length is 74.96 mm, compute its original length if the deformation is totally elastic. The elastic and shear moduli for this alloy are 105 GPa and 39.7 GPa, respectively.
Answer:
L = 75.25 mm
Explanation:
First we need to find the lateral strain:
Lateral Strain = Change in Diameter/Original Diameter
Lateral Strain = (20.025 mm - 20 mm)/20 mm
Lateral Strain = 1.25 x 10⁻³
Now, we will find the Poisson's Ratio:
Poisson's Ratio = (E/2G) - 1
where,
E = Elastic Modulus = 105 GPa
G = Shear Modulus = 39.7 GPa
Therefore,
Poisson's Ratio = [(105 GPa)/(2)(39.7 GPa)] - 1
Poisson's Ratio = 0.322
Now, we find longitudinal strain by following formula:
Poisson's Ratio = - Lateral Strain/Longitudinal Strain
Longitudinal Strain = - Lateral Strain/Poisson's Ratio
Longitudinal Strain = - (1.25 x 10⁻³)/0.322
Longitudinal Strain = - 3.87 x 10⁻³
Now, we can fin the original length:
Longitudinal Strain = Change in Length/L
where,
L = Original Length = ?
Therefore,
- 3.87 x 10⁻³ = (74.96 mm - L)/L
(- 3.87 x 10⁻³)(L) + L = 74.96 mm
0.99612 L = 74.96 mm
L = 74.96 mm/0.99612
L = 75.25 mm

Assume we have only single 2-input OR gate as well as three NOT gates. We need to create a 2-input AND gate. Make a logic circuit that is equivalent to a 2-input AND gate using the gates we have
We can create a 2-input AND gate by connecting two of the NOT gates to the single OR gate such that the output of the OR gate is negated twice. This logic circuit will be equivalent to a 2-input AND gate.
We can create a 2-input AND gate using the components we have - a single 2-input OR gate and three NOT gates. The idea here is to effectively negate the output of the OR gate twice. To do this, we need to connect two of the NOT gates in series, with the output of the OR gate connected to the input of the first NOT gate. The output of the second NOT gate will be the output of the logic circuit, which will be equivalent to a 2-input AND gate. By negating the output of the OR gate twice, we effectively make the logic circuit output a high signal only when both the inputs to the OR gate are high. When either of the two inputs are low, the OR gate output will be low, which will then be negated twice to give a low output. This is the same behaviour as a 2-input AND gate, and hence the circuit is equivalent to a 2-input AND gate.

A gas at 20 degree C may be considered rarefied, deviating from the continuum concept, when it contains less than 10^12 molecules per cubic millimeter. If Avogadro's number is 6.023 E23 molecules per mole, what absolute pressure (in Pa) for air does this represent?
The absolute pressure of air at which it deviates from the continuum concept can be calculated using the given information.
To calculate the absolute pressure, we need to determine the number of molecules per cubic millimeter. Given that a gas is considered rarefied when it contains less than 10^12 molecules per cubic millimeter, and Avogadro's number is\(6.023 × 10^23\) molecules per mole, we can use these values to find the absolute pressure.
To convert from molecules per cubic millimeter to moles per cubic millimeter, we divide the given value by Avogadro's number:
\(10^12 molecules/mm^3 / (6.023 × 10^23 molecules/mol) = 1.66 × 10^-12 mol/mm^3\)
Now, we can convert the number of moles per cubic millimeter to pressure in Pascals (Pa) using the ideal gas law equation:
PV = nRT
Assuming the gas is at a temperature of 20 degrees Celsius, which is 293.15 Kelvin, and using the ideal gas constant R = 8.314 J/(mol·K), we can rearrange the equation to solve for pressure:
P = (nRT) / V
Given that the volume is 1 mm^3, the number of moles per cubic millimeter is 1.66 × 10^-12 mol/mm^3, and the temperature is 293.15 K, we can calculate the absolute pressure as:
\(P = (1.66 × 10^-12 mol/mm^3) × (8.314 J/(mol·K)) × (293.15 K) / (1 mm^3)P ≈ 3.89 × 10^-6 Pa\)
Therefore, the absolute pressure for air when it deviates from the continuum concept is approximately 3.89 × 10^-6 Pa.
