For the specified values, the saturated density is 430 Kg/m3, whereas the bulk density is 2700 Kg/m3.

Given data

Void ratio e = 0.43

Specific gravity Gs = 2.7

density of water ρw = 1000 Kg/m^3

1)Mass of soil solids = Gs ρw

= 2.7*1000

= 2700 Kg/m^3

2)Value of eρw

= 0.43*1000

=430 Kg/m^3

Soil compaction is indicated by bulk density. It is determined by dividing the dry weight of the soil by its volume.

Both the volume of soil particles and the volume of soil particle pores are included in this volume. Typically, bulk density is stated in g/cm3.

The Influence of Inherent - The density of soil mineral (sand, silt, and clay) and organic matter particles, as well as how they are packed, all affect bulk density. As a general rule, the bulk density of most rocks is 2.65 g/cm3, hence the optimal soil is one with a medium texture.

The component of forces acting on member ABD Aₓ and A[tex]_y[/tex] are 1390lb← and 740lb↑ respectively.

A component is a piece that makes up something. Similar to how parts of a force are expressed by pointing in their directions, so does a force. These are typically categorised as vertical and horizontal components.

If I push you horizontally with some force, the horizontal force component is equal to the total force, and the vertical force component is equal to zero.

The horizontal component of force is F·cos30° and the vertical component is F·cos30 if a bullet is fired at, say, a 30° angle to the horizontal, and you draw a right-angled triangle with the bullet's path as the hypotenuse (though it's parabolic for long distances).

Calculate the reaction force acting at E

Take the moments about point A

[tex]\begin{gathered}\\\sum M_A=0 \\\left(E_x\right)(12)-(430)(15)-(310)(33)=0 \\E_x=1390 lb \\A_x=1390 lb\\\\\end{gathered}[/tex]

Now,

[tex]A_y - 430 -310 = 0\\A_y = 740 \ lb[/tex]

Take the moments about point B

[tex]\Sigma M_b =0\\(D-y)(18)- 740\times 6 = 0\\D-y=246.55\lb[/tex]

Substitute 2780 lb for Dx

[tex]B_x+D_x-1390=0[/tex]

[tex]\\B_x+2780-1390=0 \\B_x=-1390\ \text{lb}[/tex]

Consider the equilibrium equation along y axis in the member ABD, Substitute 246.66 lb for Dy

[tex]\\B_y+D_y+740=0\\B_y+246.66+740=0 \\B_y=-986.66 \mathrm{lb}\end{gathered}[/tex]

Using the free body diagram of member ABD and the equilibrium equations the component forces Bx and By have been calculated. Since we got negative values for Bx and By that means the direction of forces Bx and By are opposite to the assumed direction.

Thus, The component forces Aₓ and A[tex]_y[/tex] are 1390lb← and 740lb↑ respectively.

The power required for this mixer is 14700000 Watts.

The power required for the mixer can be calculated using the following formula:

Power = (G^2 * Detention Time) / (Flow Rate * 8.34)

where G is the mixer's specific energy input in m^3/s^3, Detention Time is the time the liquid spends in the mixer in seconds, Flow Rate is the flow of the liquid through the mixer in m^3/s, and 8.34 is a constant.

Plugging in the given values:

Power = (700^2 * 30) / (20000/86400 * 8.34)

Power = (490000 * 30) / (0.002314814814814815)

Power = 14700000

Answer:

Explanation:

To determine the normal stress in the brass core and aluminum plates, we can use the equation of equilibrium:

F = P = A_core * sigma_core + 2 * A_aluminum * sigma_aluminum

where F is the applied force, P is the magnitude of the force, A_core is the cross-sectional area of the brass core, sigma_core is the normal stress in the brass core, A_aluminum is the cross-sectional area of the aluminum plates, and sigma_aluminum is the normal stress in the aluminum plates.

We know that h = 10 mm, and since the cross-sectional area of the brass core is the same as that of the aluminum plates, we can find the cross-sectional area by multiplying h by the width of the block.

A_core = A_aluminum = h * width

We can now use the equation of equilibrium to find the normal stress in the brass core and aluminum plates:

450kN = A_core * sigma_core + 2 * A_aluminum * sigma_aluminum

sigma_core = P / A_core

sigma_aluminum = (P - A_core * sigma_core) / (2 * A_aluminum)

Note that you would need to know the width of the block in order to complete the calculation.

Maximum absolute values of the shear = 28 KN

Maximum absolute values of bending moment = 5.7 KN.m

A) We can see the beam loaded in the first image attached.

For the shear diagram, let us calculate the shear from point load to point load.

From A to C, summing vertical to zero gives; ∑fy = 0: -20 - V = 0

V = -20 KN

From C to D, summing vertical to zero gives; ∑fy = 0: -20 + 48 - V = 0

V = 28 KN

From D to E, summing vertical to zero gives; ∑fy = 0: -20 + 48 - 20 - V = 0

V = 8 KN

From E to B, summing vertical to zero gives; ∑fy = 0: -20 + 48 - 20 - 20 - V = 0

V = -12 KN

For the bending moment diagram, let us calculate the bending moment from point load to point load.

At point A, the bending moment would be zero. Thus, M_A = 0 KN.m

At point C, taking moment about point C and equating to zero gives;

M_C = 0. Thus; 20(0.225) + M = 0

M = -4.5 KN.m

At point D, taking moment about point D and equating to zero gives;

M_D = 0. Thus; 20(0.525) - 48(0.3) + M = 0

M = 3.9 KN.m

At point E, taking moment about point E and equating to zero gives;

M_D = 0. Thus; 20(0.75) - 48(0.525) + 20(0.225) + M = 0

M = 5.7 KN.m

At point B, taking moment about point E and equating to zero gives;

M_E = 0. Thus; 20(1.05) - 48(0.825) + 20(0.525) + (20 * 0.3) + M = 0

M = 2.1 KN.m

What is axial load?
Axial load, also called thrust load, is a type of force that is applied along the axis of a component or structure. It is a compressive or tensile force which acts in the direction of the axis of an object. It is usually caused by an external force, such as an applied load, or by an internal force, such as the thrust generated by a motor. Axial loads can be static, meaning that the force is constant, or dynamic, meaning that the force changes over time. Axial load can cause deformation, or bending of the component. It can also cause stress, which can lead to fatigue and failure.

The coordinate direction angles of F in order to produce the maximum moment about the a-a axis is 14.49Nm and this moment is 15Nm.

What is direction?
Direction is a term that can refer to a number of different concepts. Generally speaking, direction is a line of travel or an orientation in physical space. Direction can also refer to a goal or purpose for which one is striving, such as a career path or a life path. Directions can also be given in terms of instructions, as in directions for using an appliance, directions for playing a game, or even directions for a recipe.

The moment of the force F about the a-a axis is given by:

M = F × d × sin(\alpha + \gamma)

M = 30N × 0.5m × sin(60° + 45°)

M = 30N × 0.5m × 0.9659

M = 14.49Nm

The coordinate direction angles of F in order to produce the maximum moment about the a-a axis are (45°, -45°). The maximum moment is given by:

Answer:

The wheel will go through 1146 revolutions in 5 minutes.

Explanation:

We can the formula:

[tex]\boxed{\omega = \frac{2 \pi}{T}}[/tex]

where

ω ⇒ angular speed (24 rad/s),

T ⇒ time period (? s),

and solve for T to find the time it takes for the wheel to complete one revolution.

⇒  [tex]24 = \frac{2 \pi}{T}[/tex]

⇒  [tex]T = \bf \frac{2 \pi}{24}[/tex]  s

This means it takes [tex]\bf \frac{2 \pi}{24}[/tex] seconds for the wheel to complete one revolution.

Now, using the unitary method,

In [tex]\frac{2 \pi}{24}[/tex] seconds          ⇒    1 revolution completed

In 1 second              ⇒    1 ÷ [tex]\frac{2 \pi}{24}[/tex]   =  [tex]\frac{24}{2 \pi}[/tex]  revolutions completed

In (5 × 60 = ) 300s  ⇒     [tex]\frac{24}{2 \pi}[/tex]   ×  300   = 1145.9
