Determine the percentage of this moment that is resisted by the web d of the beam.

Answers

Answer 1

We have a beam with flange dimensions of 6 x 2 1/2 inches, and a web of 1/4 inch thickness and 6 inches depth. The beam is subject to a bending moment of 75,000 lb-inches. We need to determine the percentage of this moment that is resisted by the web "d" of the beam.

Determination of the area of the web d of the beam:For rectangular sections, the moment of inertia about an axis through the center of gravity is given by the equation:I=(bh³)/12where,b = width of the sectionh = height of the sectionUsing the above formula, the moment of inertia of the web d about its center of gravity will be,I = (1/4) (6)³ /12= (0.25) (216)/12= 4.5 in⁴The plastic section modulus of the web d of the beam is given by the equation:Z = I / (d/2)= 4.5 / (6/2)= 1.5 in³We know that the elastic section modulus is given by the equation:Z = I / ywhere,y = distance from the neutral axis to the extreme fiber.Z = I / y⇒ y = I / Z= 4.5 / 1.5= 3 inTherefore, the distance from the neutral axis to the extreme fiber is 3 inches

Determination of the area of the flanges:

For rectangular sections, the moment of inertia about an axis through the center of gravity is given by the equation:I=(bh³)/12where,b = width of the sectionh = height of the sectionUsing the above formula, the moment of inertia of the flanges about the centroidal axis of the section will be:I = (2.5) (6)³ /12+ (6) (2.5) ³ /12= 37.5 in⁴The plastic section modulus of the flanges is given by the equation:Z = I / (d/2)= 37.5 / (6/2)= 12.5 in³We know that the elastic section modulus is given by the equation:Z = I / ywhere,y = distance from the neutral axis to the extreme fiber.The distance from the neutral axis to the extreme fiber of the flanges will be half of the depth of the section, which is 3 inches.

Determination of the percentage of the moment resisted by the web d:

Let M be the bending moment acting on the beam. Then, the stress in the web d will be:s = M y / Zwhere,y = distance from the neutral axis to the extreme fiberZ = elastic section modulus of the section at the location of interestM = 75,000 lb-inchesS = 75,000 x 3 / 12.5= 18,000 psi

Therefore, the percentage of the moment resisted by the web d is determined as follows:

Percentage of moment resisted by the web d = Stress in web d / Compressive stress in flange x 100= 18,000 / 20,000 x 100= 90%Therefore, the percentage of this moment that is resisted by the web d of the beam is 90%.

Consider the flow of a uniform stream of speed V1 at an angle of attack alpha past a biplane consisting of two- flat plate airfoils of chord c at a distance h apart (no stagger). Find the lift coefficient for each airfoil using a single vortex to represent each one

Answers

The lift coefficient for each airfoil can be found by using the single vortex method. For a uniform stream with speed V1 at an angle of attack alpha.

A biplane with flat plate airfoils of chord c at a distance h apart, the lift coefficient can be calculated by dividing the total vortex strength by the product of the velocity and the reference area.

The lift coefficient represents the lift generated by an airfoil relative to its size and the flow conditions. In this case, we can use the single vortex method, which simplifies the flow field by representing each airfoil as a single vortex. To find the lift coefficient for each airfoil, we need to calculate the total vortex strength (Γ) for each vortex, and then divide it by the product of the velocity (V1) and the reference area (c). The reference area is the area over which the lift force is evaluated, and in this case, it is the airfoil chord (c). By dividing the total vortex strength by the velocity and reference area, we obtain the lift coefficient for each airfoil.

The spoked wheel of radius r-705 mm is made to roll up the incline by the cord wrapped securely around a shallow groove on its outer rim.
If the cord speed at point P is v-2.0 mys, determine the velocities of points A and B. No slipping occurs. Answers: Ve- mis

Answers

GivenDataRadius of the spoked wheel, r = 705 mmCord speed at point P, v = 2.0 m/sVelocity of point E = VeWe know that linear velocity (v) = angular velocity (ω) × radius (r)We can find the angular velocity using the formula:ω = v / rω = 2 / 0.705= 2.84 rad/s

We know that the velocity of point A is perpendicular to the incline and the velocity of point E is parallel to the incline.As no slipping occurs, the velocity of point B is zero.The velocity of point E is given byVe = ω × r = 2.84 × 0.705 = 2.00 m/sLet VA be the velocity of point A. Then we can write:VA / Ve = AB / AEBut AB = 2r and AE = r + hSo we haveVA / 2 = AB / (r + h)VA / 2 = 2r / (r + h)VA = 4r / (r + h)Substitute the values to obtainVA = 4 × 705 / (705 + 300) = 2.22 m/sTherefore, the velocities of points A and B are VA = 2.22 m/s and VB = 0 m/s respectively.Note that the solution has a word count of 159 words.

#SPJ11

According to the information, the velocity of point A is v = 1.0 m/s and the velocity of point B is v = 2.0 m/s.

How to calculate the velocity of point A and point B?

Fist we have to consider that since no slipping occurs, the linear velocity of any point on the wheel must be equal to the tangential velocity of the cord. At point P, the cord speed is given as v = 2.0 m/s.

Now, to determine the velocities of points A and B, we need to consider the relationship between linear velocity, angular velocity, and radius. The linear velocity of a point on the wheel is equal to the product of the angular velocity and the radius of the wheel.

Additionally, the radius of the wheel is given as r = 705 mm, which is equivalent to 0.705 m, we can calculate the angular velocity (ω) of the wheel by dividing the linear velocity of point P (v) by the radius (r).

ω = v / r = 2.0 m/s / 0.705 m ≈ 2.836 rad/s

Now, we can calculate the velocities of points A and B using the angular velocity and their respective radii.

Velocity of point A:

v_A = ω * r_A = 2.836 rad/s * r_A

Velocity of point B:

v_B = ω * r_B = 2.836 rad/s * r_B

Since the radius of point A (r_A) is 0.705 m, the velocity of point A is:

v_A = 2.836 rad/s * 0.705 m = 2.0 m/s

Since the radius of point B (r_B) is twice the radius of point A, i.e., 2 * 0.705 m = 1.41 m, the velocity of point B is:

v_B = 2.836 rad/s * 1.41 m = 4.0 m/s

According to the above, the velocity of point A is v_A = 2.0 m/s and the velocity of point B is v_B = 4.0 m/s.

A∩A^2=∅
(b,a)∈A^2

Answers

The false statement is A∩A^2=∅.

Given, A = {a, b} and B = {1, 2, 3}

Firstly, we need to understand what the terms mean in the given statements:

Let A = {a, b} and B = {1, 2, 3}. Then, A × B is a Cartesian product of A and B.

This means that A × B = {(a,1), (a,2), (a,3), (b,1), (b,2), (b,3)}.(b,3) ∈ A × B, which is true.

A^2 is a set of all possible ordered pairs (a, b) where a and b are from A.

Therefore, A^2 = {(a, a), (a, b), (b, a), (b, b)}.(b, a) ∈ A^2, which is true.

Now, A ∩ A^2 is an intersection of two sets, A and A^2. Since A = {a, b} and A^2 = {(a, a), (a, b), (b, a), (b, b)}, then A ∩ A^2 = {(a, a), (b, b)}. This means that A ∩ A^2 ≠ ∅, and the statement A∩A^2=∅ is false.

|A × B| is the number of elements in A × B. Since A × B = {(a,1), (a,2), (a,3), (b,1), (b,2), (b,3)}, then |A × B| = 6. This means that |A × B| = 5 is false.

The velocity of the tugboat after the cable becomes taut is:_________

Answers

The velocity when the cable becomes taut can be obtained by assuming

that the tugboat collides with a barge moving in the same direction.

Response (approximate value):

The velocity of the tugboat after the cable becomes taut is: 5.824 ft./s.

How is the law of conservation of linear momentum used to calculate the speed of the tugboat?

Weight of the tugboat, m₁ = 240–ton

Speed of the tugboat, v₁ = 6 ft./s

Weight of the barge, m₂ = 100–ton

Rate at which the towing cable is being unwound, v₂ = 5.4 ft./s

Required:

Velocity of the tugboat after the cable becomes taut.

Solution:

m₁ = 240 ton = 240,000 kg

m₂ = 100 ton = 100,000 kg

The velocity of the barge at rest is assumed to be the rate at which the cable is being unwound, and in the direction of the tugboat.

According to the law of conservation of linear momentum, we have;

m₁ × v₁ + m₂ × v₂ = (m₁ + m₂) × v₃

Which gives;

240 × 6 + 100 × 5.4 = (240 + 100) × v₃

1980 = 340 × v₃

Which gives;

\(v_3 = \dfrac{1980}{340} = \dfrac{99}{17} = 5\frac{14}{17} \approx \mathbf{ 5.824}\)
