Pier and post foundations with beams or girders must have at least a ____ inch bearing on the foundation.
Answers
Pier and post foundations with beams or girders must have at least a 4-inch bearing on the foundation.
Beams are the principal load-bearing component of the structural frame system. Beams are designed to bend in order to withstand and disperse the load. Girders, on the other hand, are stiffer since they support the beams and provide the structure's principal horizontal support. The girder is designed to carry large, all-encompassing loads like structural pillars or beam reactions. In general, a girder is there to support other beams and convey load-bearing weight.
A beam is an essential component of any structural steel frame and is intended to sustain distributed loads such as a roof structure. Their primary function in a building is to maintain its strength and stability. Beams are the ideal material.

Answers
The answers to dry unit weight, void ratio, porosity, degree of saturation, volume occupied by water are respectively;
γ_d = 108.93 lb/ft³; e = 0.56; n = 0.36; S = 0.58; V_w = 0.021 ft³
Calculation of Volume and Weight of soil
We are given;
Moist weight; W = 12.2 lb
Volume of moist soil; V = 0.1 ft³
moisture content; w = 12% = 0.12
Specific gravity of soil solids; G_s = 2.72
A) Formula for dry unit weight is;
γ_d = γ/(1 + w)
where γ_w is moist unit weight as;
γ_w = W/V
γ_w = 122/0.1 = 122 lb/ft³
Thus;
γ_d = 122/(1 + 0.12)
γ_d = 108.93 lb/ft³
B) Formula for void ratio is;
e = [(G_s * γ_w)/γ_d] - 1
e = [(2.72 * 122)/108.93] - 1
e = 0.56
C) Formula for porosity is;
n = e/(1 + e)
n = 0.56/(1 + 0.56)
n = 0.36
D) Formula for degree of saturation is;
S = (w * G_s)/e
S = (0.12 * 2.72)/0.56
S = 0.58
E) Volume occupied by water is gotten from;
V_w = S*V_v
where;
V_v is volume of voids = nV
V_v = 0.36*0.1
V_v = 0.036 ft³
Thus;
V_w = 0.58 * 0.036
V_w = 0.021 ft³

Given grammar,S → dBeB → BcB → cNow we have to create a predictive parser for the given grammar. The first thing that we will do is to remove the left recursion from the grammar as it is required to create predictive parsers from the grammar.
S → dBeB → cB`B` → εS → dBeB → cS`S` `→ BcS` `| ε`After eliminating the left recursion, we will construct the parsing table. We will first find the first and follow sets of all the non-terminals.

A new forging plant must supply parts to a construction equipment manufacturer. Forging is a hot operation, so the plant will operate 24 hr/day, five days/wk, 50 wk/yr. Total output from the plant must be 800,000 forgings per year in batches of 1,250 parts per batch. Anticipated scrap rate = 3%. Each forging cell will consist of a furnace to heat the parts, a forging press, and a trim press. Parts are placed in the furnace an hour prior to forging; they are then removed, forged, and trimmed one at a time. The complete cycle takes 1.5 min per part. Each time a new batch is started, the forging cell must be changed over, which consists of changing the forging and trimming dies for the next part style. This takes 3.5 hr on average. Each cell is considered to be 96% reliable (availability = 96%) during operation and 100% reliable during changeover.
(a) Determine the number of forging cells that would be required in the new plant.
(b) What is the proportion of time spent in setup for each batch?
Answers
The new plant would require 4 forging cells.
The proportion is 10.07%.
How to solve for the number of forging cells that would be required in the new plant.Total available working time per year:
24 hours/day * 5 days/week * 50 weeks/year
= 6,000 hours/year
Total parts required including scrap:
800,000 forgings / (1 - 0.03)
= 800,000 / 0.97
≈ 824,742 forgings
Number of batches required:
824,742 forgings / 1,250 parts per batch
≈ 660 batches
Total forging time (excluding changeover time) for 824,742 parts:
1.5 minutes/part * 824,742 parts * (1 hour / 60 minutes)
≈ 20,618.55 hours
Total changeover time for 660 batches:
660 batches * 3.5 hours/changeover
≈ 2,310 hours
Total time required to produce 824,742 forgings, including changeovers:
20,618.55 hours + 2,310 hours
≈ 22,928.55 hours
Now, considering the availability of each cell during operation (96%):
Effective operation time required
= 22,928.55 hours / 0.96
≈ 23,883.49 hours
Now, we can determine the number of forging cells needed to meet production requirements:
Number of cells = Total time required / Total available working time
= 23,883.49 hours / 6,000 hours/year
≈ 3.98
Therefore, the new plant would require 4 forging cells.
B. Proportion of time spent in setup = 2,310 hours / 22,928.55 hours ≈ 0.1007
The proportion of time spent in setup for each batch is approximately 10.07%.

a current amplifier supplies i rna to a load resistance of i k.o. when the load resistance is increased to 12 kn, the output current decreases to 0.5 ma. what are the values of the short-circuit output current and the output resistance of the amplifier?
Answers
We can use the voltage divider rule to calculate the output current from the amplifier:
\(Vout = iRNA * RL/(RA + RL)\)
When RL is i kΩ,
\(Vout = iRNA * i kΩ/(RA + i kΩ)\)
When RL is 12 kΩ,
\(Vout = 0.5 mA * 12 kΩ/(RA + 12 kΩ)\)
Since the voltage gain of the amplifier is infinite, the output voltage is equal to the input voltage.
we can equate the two values of Vout as follows:
\(iRNA * i kΩ/(RA + i kΩ)\)
\(= 0.5 mA * 12 kΩ/(RA + 12 kΩ)\)
Simplifying this equation and solving for RA, we get:
RA = 4 kΩ
The short-circuit output current is the current flowing through RA and is given by:
ISC = Vinput/RA
Where Vinput is the voltage applied to the input of the amplifier.
Vinput = iRNA * RA
ISC = iRNA/RA
\(= iRNA/4 kΩ\)
\(= (iRNA/1000) / 4 A\)
\(= 0.25 iRNA mA\)
The short-circuit output current is 0.25 iRNA mA. the output resistance of the amplifier is 4 kΩ and the short-circuit output current is 0.25 iRNA mA.

Two chambers with the same fluid at their base are
separated by a 30-cm-diameter piston whose weight is 25
N. Calculate the gage pressures in chambers A and B
Answers
Answer:
Pgage at A = 101.30354 kPa
Pgage at B = 101.29646 kPa.
Explanation:
To calculate the gauge pressures in chambers A and B, we need to use the formula:
Pressure = Force / Area
where force is the net force acting on the piston and area is the cross-sectional area of the piston.
First, let's calculate the net force acting on the piston. We know that the weight of the piston is 25 N, which is acting downwards. We also know that the piston is in equilibrium, so the net force acting on it is zero. Therefore, there must be an upward force acting on the piston that is equal in magnitude to the weight of the piston. This upward force is the pressure difference between the two chambers pushing up on the piston.
The area of the piston is given by:
Area = pi * (diameter/2)^2
= pi * (30 cm / 2)^2
= 706.9 cm^2
Now we can calculate the pressure difference between the two chambers:
Pressure difference = Force / Area
= 25 N / 706.9 cm^2
= 0.0354 N/cm^2
Since the fluid in both chambers is at the same level, the pressure in chamber A is equal to the atmospheric pressure plus the pressure difference, and the pressure in chamber B is equal to the atmospheric pressure minus the pressure difference. Assuming the atmospheric pressure is 101.3 kPa, we can calculate the gauge pressures in chambers A and B as follows:
Pressure in A = Atmospheric pressure + Pressure difference
= 101.3 kPa + 0.0354 N/cm^2
= 101.3 kPa + 0.00354 kPa
= 101.30354 kPa
Pressure in B = Atmospheric pressure - Pressure difference
= 101.3 kPa - 0.0354 N/cm^2
= 101.3 kPa - 0.00354 kPa
= 101.29646 kPa
Therefore, the gauge pressure in chamber A is 101.30354 kPa and the gauge pressure in chamber B is 101.29646 kPa.

A simple Rankine cycle uses water as the working fluid. The boiler operates at 6000 kPa and the condenser at 50 kPa. At the entrance of the turbine the temperature is 450 deg C. The isentropic efficiency of the turbine is 94 percent, pressure and pump losses are negligible, and the water in the condenser is subcooled by 6.3 degC. The boiler is sized for a mass flow rate of 20 kg/s. Determine the rate at which heat is added in the boiler, the power required to operate the pumps, the net power produced by the cycle, and the thermal efficiency.
Answers
Answer:
the rate at which heat is added in the boiler = 59597.4 kW
the power required to operate the pumps = 122.57 kW
The net power produced by the cycle = 17925 kW.
The thermal efficiency = 30%.
Explanation:
The specific enthalpy of saturated liquid is equal to the enthalpy of the first point which is equal to 314 kJ/ kg.
The second enthalpy is calculated from the pump work. Therefore, the second enthalpy = first enthalpy point + specific volume of water [ the pressure of the boiler - the pressure of the condenser].
The second enthalpy = 314 + 0.00103 [ 6000 - 50 ] = 320.13 kJ/kg.
The specific enthalpy for the third point = 3300 kJ/kg.
Therefore, the rate at which heat is added in the boiler = 20 × [3300 - 320.13] = 59597.4 kW.
The rate at which heat is added in the boiler = 59597.4 kW.
Also, the power required to operate the pumps = 20 × 0.00103 [6000 - 50] = 122.57 kW.
The power produced by the turbine = 20 [ 300 - ( the fourth enthalpy value)].
The fourth enthalpy value = 3300 - 0.94 [ 3300 - 2340] = 2397.6 kJ/kg
Thus, the power produced by the turbine = 20 [ 300 - 2397.6] = 18048 kW.
The power produced by the turbine = 18048 kW.
The net power produced = 18048 + 122.57 = 17925 kW.
The thermal efficiency = [net power produced] / [the rate at which heat is added in the boiler].
The thermal efficiency = 17925/ 59597.4 = 30%.

b. 14.3

Answers
Answer:
Weight Percentage of Ash = 3.4
Explanation:
Given - Coal containing 21% ash is completely combusted, and the ash is 100% removed in a water contact scrubber. If 10,000 kg of coal is burned per hour with a scrubber flow rate of 1.0 m3/min.
To find - the weight percentage of the ash in the water/ash stream leaving the scrubber is most nearly ?
Solution -
Given that,
Coal Burned Rate = 10,000 kg/hr
= \(\frac{10,000}{60 min} * 1 hr *\frac{kg}{hr}\)
= 166.6666 kg/min
⇒Coal Burned Rate = 166.6666 kg/min
Now,
Given that,
Ash content in coal = 21 %
⇒Ash in (coal that burned) = 166.6666 × \(\frac{21}{100}\) kg/min
= 34.9999 ≈ 35 kg/min
⇒Ash in (coal that burned) = 35 kg/min
Now,
We know,
Density of water = 1000 kg/m³
Now,
Water flow Rate = \(1\frac{m^{3} }{min} * density\)
= 1000 kg/min
⇒Water flow Rate = 1000 kg/min
Now,
Total Mass flow Rate of (Water + Ash stream) = ( 1000 + 35) kg/min
= 1035 kg/min
⇒Total Mass flow Rate of (Water + Ash stream) = 1035 kg/min
So,
Weight Percentage of Ash = (Weight of Ash ÷ Total weight of Stream) × 100
= (35 ÷ 1035) × 100
= 3.38 ≈ 3.4
∴ we get
Weight Percentage of Ash = 3.4

It means that the gas with the lowest molecular weight will have the highest effusion rate.
What has the highest rate of effusion?The given gases' effusion rates are listed in order from highest to lowest. The effusion rate of a hydrogen molecule is the highest, whereas that of a hydrocarbon is the lowest.
A gas will effuse faster when it is lighter and more slowly when it is heavier. Helium (He) will have the highest rate of effusion since it has the lowest molecular weight (atomic weight, in this example).
The following equation can be used to compare the rate of effusion for two gases: The effusion rates in this case are inversely related to the square root of the gas molecules' masses. A container contains an amalgam of neon and argon gas.
