The acceleration of block A is 8.4949 and block B is 4.2475 ft/s² while the tension is the cable is 121.168 lb.
What is tension?When there are two forces acting on the ends of a cable, rope, wire, or string, it is said to be under tension. The cable has a one-direction pull along its entire length, pulling equally in both directions on objects at either end.
Tension can also be used to describe the forces that are acting on both ends of the two elements. In other words, tension's polar opposite is compression.
Physical objects must exert some force on one another in order to make contact with one another. Depending on the kind of object, each of these contact forces will be unique.
Take a section about the rope near block B and using the show datum
SB + (SB - SA) = l
2SB - SA = l
2SB - SA = 0
2aB - aA = 0
aA = 2aB
Take FBD of block-A
(Upward+) ∑Fₓ = mAaA
T - W[tex]_A[/tex]sin20° = mAaA
T - 200sin20° = (W[tex]_A[/tex]/g)(2aB)
T = 200sin20° + (W[tex]_A[/tex]/g)(2aB)
Take FBD of block-B;
(Downward+) ∑Fₓ = mBaB
W[tex]_B[/tex]cos20° - 2T = mAaA
300cos20° - 2(200sin20° + (W[tex]_A[/tex]/g)(2aB)) = (W[tex]_B[/tex]/g)(a[tex]_B[/tex])
300cos20° - 2(200sin20° + (200/32.2)(2aB)) = (300/32.2)(a[tex]_B[/tex])
a[tex]_B[/tex] = 4.2475 ft/s²
Acceleration of A is given as;
⇒ aA = 2aB
⇒ aA = 8.4949 ft/s²
Tension is given as;
T = 200sin20° + (200/32.2)(2(4.2475))
T = 121.168 lb
Thus, the acceleration of block A is 8.4949 and block B is 4.2475 ft/s² while the tension is the cable is 121.168 lb.

The cantilevered rectangular bar is subjected to the force of 5 kip. Determine the principal stress at point A and B
To determine the principal stress at point A and B on a cantilevered rectangular bar subjected to a force of 5 kip, a detailed analysis of the structure would need to be performed.
Principal Stress Calculation-Rectangular BarInvolve determining the distribution of stresses throughout the bar due to the applied load, and then determining the maximum and minimum principal stresses at points A and B.
Assuming a rectangular cross section, The principal stresses can be calculated by Mohr's Circle. The equations for principal stresses are:
σ1 = (σx + σy + √((σx - σy)² + 4τxy²))/2
σ2 = (σx + σy -√((σx - σy)² + 4τxy²))/2
Where, σx and σy are the normal stresses, and τxy is the shear stress.
It is important to note that the analysis would also require information about the material properties, cross-sectional dimensions, and boundary conditions of the bar, as well as a detailed understanding of the loading conditions and any other factors that may affect the distribution of stresses in the structure.

Transformers are electronic devices that are used to change the voltage, current, or frequency of alternating current (AC) electricity. They are important components in electrical power systems, allowing power to be transmitted over long distances and between different voltage levels. Transformers consist of two coils of wire, known as the primary and secondary windings, with an iron core in the middle that serves to link the two coils together. When an alternating current is applied to the primary winding, it creates an alternating magnetic field, which in turn induces a voltage in the secondary winding.

This medium (or any other, for that matter) can be cleaned at a backwash velocity of 0.3 m/min if the fluidization is provided by air scour. Calculate the volume of water saved during a 10 min backwash of a 2 by 4 m filter if air scours is used. If the cost of water production is 25 BDT/m3, how much money would be saved per year by air fluidization if the filter runs on average 2 days in length?
The backwash velocity necessary to expand a sand filter with an effective size of 0.6 mm and a uniformity coefficient of 1.3 is 15.6 mm/min or 0.156 m/min
The volume of water saved during a 10 min backwash of a 2 by 4 m filter if air scours is used is 4560 L
The money that would be saved per year by air fluidization if the filter runs on average 2 days in length is 8.1*10^5 BDT/year.
How can you calculate the backwash velocity, volume of water and money to be saved?To calculate the backwash velocity necessary to expand a sand filter with an effective size of 0.6 mm and a uniformity coefficient of 1.3, the following formula can be used:
Backwash velocity = (effective size * uniformity coefficient) / 3
Plugging in the values, we get:
Backwash velocity = (0.6 mm * 1.3) / 3 = 0.26 mm/s
To convert this to meters per minute, we multiply by 60:
Backwash velocity = 0.26 mm/s * 60 = 15.6 mm/min or 0.156 m/min
The fluidization is provided by air scour, which can clean the medium at a backwash velocity of 0.3 m/min.
To calculate the volume of water saved during a 10 min backwash of a 2 by 4 m filter if air scours is used, we can use the formula:
Volume of water saved = (filter area * backwash time * water flow rate) - (filter area * backwash time * air flow rate)
Plugging in the values, we get:
Volume of water saved = (2 m * 4 m * 600 L/min) - (2 m * 4 m * 0.3 m/min) = 4800 L - 240 L = 4560 L
If the cost of water production is 25 BDT/m3, the money saved per year by air fluidization if the filter runs on average 2 days in length can be calculated as:
Money saved per year = (volume of water saved per backwash * number of backwashes per year) * (cost of water production)
Plugging in the values, we get:
Money saved per year = (4560 L/backwash * 365 / 2 days/year) * 25 BDT/m3 = 8.1*10^5 BDT/year

Calculate v and ix in the circuit of Fig. 2.79.
The expression for the voltage across the resistor is v=6V and I^ x=-4A
Step by step explanation:
The current in the loops are, I^ 1 in loop 1 and I^2 in loop 2
Apply Kirchhoff's voltage law to loop 1.
10=12i^ 1 +4
10-4=12i^ 1
12i^ 1=6
I^ 1 = 6/12=0.5 A
Write the expression for the voltage across the resistor:
V=12I^ 1
=12(0.5)
v=6V
Apply KVL in loop 2:
3i^ x+16=4
3i^ x=-12
I^ x=-12/3
I^ x=-4A
Kirchhoff's Voltage Law describes the distribution of electrical voltage within an electrical circuit's loop, or closed conducting path. According to Kirchhoff's Voltage Law.
Any loop's algebraic sum of voltage (potential) differences must equal zero.

The device shown is used to mix soils in order to provide in-situ stabilization. If the mixer is connected to an A-36 steel tubular shaft that has an inner diameter of 3 in. and an outer diameter of 4.5 in., determine the angle of twist of the shaft at A relative to C if each mixing blade is subjected to the torques shown.
Angle of shaft twist at A with respect to C is equal to (2.12*107) * (/180) = 37,819°.
Regarding soilThe mixture of organic matter, minerals, gases, liquids, and living things that makes up soil—also referred to as earth or dirt—supports life. Some scientific interpretations differentiate between soil and dirt by limiting the former term to only displaced soil. In addition to a highly permeable phase that holds water and gases (the soil environment), soil includes a solid phase made up of minerals and organic matter (the soil composite) (the soil solution). The three states of soil - solids, liquids, and gases. Climate, relief (elevation, direction, and slope of the terrain), organisms, and the soil's parent materials (initial minerals) all play a role in the formation of soil.
