Answer:
Pressure is equal to 2900000 Newton per square m
Explanation:
The correct question is
A Ballat dancer does a pirouette on the tip of his toe if the dancer has a weight of 580 n and the tip of his ballot show measures 0.02 by 0.01 M what pressure does his to exert on the stage?
Solution
The area of the tip of the ballot show is equal to [tex]0.02 * 0.01 = 0.0002[/tex] square meter
Pressure is equal to force applied divided by the area of the contact point.
[tex]P = \frac{Force}{Area}[/tex]
Substituting the give values we get -
[tex]P = \frac{580}{0.0002} \\P = 2900000[/tex] Newton per square meter

WAY, IS:
A. Always take it
B. Never insist on it
C. Always let the other driver have
Answer:
A
Explanation:
I don`t know I need points hope it was correct.
A good safety rule, when you are sure you have a legal right of way is: B. Never insist on it.
What is safety rule?Even if you are certain that you have a legal right-of-way, it is still crucial to put safety first and avoid being overly insistent on it. When driving, safety should always come first, even if you have the right-of-way legally.
Being cautious and courteous while driving are essential components of defensive driving, and this includes letting other drivers go ahead of you if doing so will help you avoid potential collisions or problems.
Therefore the correct option is B.

3. The maximum deflection of the beam is 2.55552 inches
Explanation:
1. The height of the beam having a rectangular cross section is h = 2.5 in.
The breadth of the beam, is = 5.5 in.
The moment of inertia of a rectangular beam through its centroid is given as follows;
[tex]I_{xc}[/tex] = b·h³/12 = 5.5 × 2.5³/12 = 1375/192 = 7.161458[tex]\overline 3[/tex]
[tex]I_{xc}[/tex] = 7.161458[tex]\overline 3[/tex] in.⁴
[tex]I_{yc}[/tex] = h·b³/12 = 2.5 × 5.5³/12 = 6655/192 = 36.661458[tex]\overline 3[/tex]
[tex]I_{yc}[/tex] = 36.661458[tex]\overline 3[/tex] in.⁴
The moment of inertia about the base is given as follows;
Iₓ = b·h³/3 = 5.5 × 2.5³/3 = 625/24 = 28.6458[tex]\overline 3[/tex]
Iₓ = 28.6458[tex]\overline 3[/tex] in.⁴
[tex]I_y[/tex] = h·b³/3 = 2.5 × 5.5³/3 = 6655/48= 138.6548[tex]\overline 3[/tex]
[tex]I_y[/tex] = 138.6548[tex]\overline 3[/tex] in.⁴
2. The height of the beam having a rectangular cross section is h = 7 in.
The breadth of the beam, b = 4 in.
The moment of inertia of a rectangular beam through its centroid is given as follows;
[tex]I_{xc}[/tex] = b·h³/12 = 4 × 7³/12 = 114.[tex]\overline 3[/tex]
[tex]I_{xc}[/tex] = 114.[tex]\overline 3[/tex] in.⁴
[tex]I_{yc}[/tex] = h·b³/12 = 7 × 4³/12 = 37.[tex]\overline 3[/tex]
[tex]I_{yc}[/tex] = 37.[tex]\overline 3[/tex] in.⁴
The moment of inertia about the base is given as follows;
Iₓ = b·h³/3 = 4 × 7³/3 = 457.[tex]\overline 3[/tex]
Iₓ = 457.[tex]\overline 3[/tex] in.⁴
[tex]I_y[/tex] = h·b³/3 = 2.5 × 5.5³/3 = 149.[tex]\overline 3[/tex]
[tex]I_y[/tex] = 149.[tex]\overline 3[/tex] in.⁴
3. The deflection, [tex]\delta _{max}[/tex], of a simply supported beam having a point load at the center is given as follows;
[tex]\delta_{max} = \dfrac{W \times L^3}{48 \times E \times I}[/tex]
The given parameters of the beam are;
The length of the beam, L = 22 ft. = 264 in.
The applied load at the center, W = 750 lbs
The modulus of elasticity for Cedar = 10,000,000 psi
The height of the wood, h = 3 in.
The breadth of the wood, b = 5 in.
The moment of inertia of the wood, [tex]I_{xc}[/tex] = b·h³/12 = 5 × 3³/12 = 11.25 in.⁴
By plugging in the given values, we have;
[tex]\delta_{max} = \dfrac{750 \times 264^3}{48 \times 10,000,000 \times 11.25} = 2.55552[/tex]
The maximum deflection of the beam, [tex]\delta _{max}[/tex] = 2.55552 inches

of 250 m2, what pressure is put on the ground by the blimp?
Answer:
[tex]Pressure = 16\ pa[/tex]
Explanation:
Given
[tex]Force = 4000N[/tex]
[tex]Area = 250m^2[/tex]
Required
Determine the pressure
Pressure is calculated using:
[tex]Pressure = \frac{Force}{Area}[/tex]
Substitute values for Force and Area
[tex]Pressure = \frac{4000N}{250m^2}[/tex]
[tex]Pressure = 16N/m^2[/tex]
