the right-angle bar with equal legs weighs 6 lb and is pinned to the rectangular plate at c. the plate is free to slide in the vertical plane and the bar is prevented from rotating by the two pegs a and b. determine the horizontal acceleration a of the plate for which no force is exerted on the bar by either peg a or b. also determine the reaction force at pin c. ans: a

For the first question, the answer is that it will take approximately 0.768 years (or approximately 9.22 months) longer for the average settlement to reach 237 mm. The effective pressure on a horizontal plane at a depth of 10 meters below the ground surface is approximately 264.87 kN/m².

Here, Settlement rate = Ultimate settlement / Time

Given that the ultimate settlement is 332 mm and the time span is 3 years, the settlement rate is:

Settlement rate = 332 mm / 3 years = 110.67 mm/year

Time = (Target settlement - Average settlement) / Settlement rate

Time = (237 mm - 152 mm) / 110.67 mm/year ≈ 0.768 years

Therefore, it will take approximately 0.768 years (or approximately 9.22 months) longer for the average settlement to reach 237 mm.

b. Hence , Effective pressure = Unit weight of soil x Depth

Unit weight of soil = Specific gravity x Unit weight of water

= 2.7 x 9.81 kN/m³

≈ 26.487 kN/m³

Effective pressure = Unit weight of soil x Depth

= 26.487 kN/m³ x 10 m

= 264.87 kN/m²

Therefore, the effective pressure on a horizontal plane at a depth of 10 meters below the ground surface is approximately 264.87 kN/m².

Explanation:

It appears that you are trying to solve a problem involving an insulated rigid tank containing saturated liquid water and water vapor. To determine the volume of the tank, you will need to know the mass of the liquid water and the mass of the water vapor. The mass of the liquid water can be calculated by multiplying the mass of the water and vapor mixture by the fraction of the mixture that is liquid water (1.4 kg * 0.25 = 0.35 kg). The mass of the water vapor can be calculated by subtracting the mass of the liquid water from the total mass of the mixture (1.4 kg - 0.35 kg = 1.05 kg).

To determine the final temperature of the tank, you will need to know the amount of heat added to the tank by the electric resistor and the specific heat capacity of the water and water vapor mixture. The specific heat capacity is a measure of the amount of heat required to raise the temperature of a substance by a certain amount. The specific heat capacity of water is 4.186 J/g°C, and the specific heat capacity of water vapor is 2.080 J/g°C.

To determine the electric power rating of the resistor, you will need to know the amount of heat added to the tank by the resistor and the time over which the heat was added. The power rating of the resistor is equal to the amount of heat added to the tank divided by the time over which the heat was added.

Explanation:

Max Weber was a sociologist and political economist who developed the concept of bureaucracy, which he regarded as the most efficient form of organization. Bureaucracy is a system in which decisions are made by the top-level executives and the lower-level employees are tasked with following the rules established by the top-level executives. The following is an examination of Weber's bureaucratic blueprint and the advantages and disadvantages it has for management and workers. In addition, suggestions for how to enhance it and the challenges to the efficacy of those suggestions will be discussed.

Advantages of Weber's Bureaucratic Blueprint

Weber's bureaucratic blueprint has several advantages for both management and workers. For management, bureaucracy is an effective way to manage resources, minimize waste, and increase productivity. It is based on a clear chain of command, which ensures that decisions are made by those who are qualified to make them and that all workers know their place in the organization. It also provides a sense of stability and consistency that can be reassuring to workers.

For workers, bureaucracy provides a clear set of rules and procedures to follow, which can help to eliminate ambiguity and reduce the risk of errors. It also provides a clear path for promotion and career advancement based on merit, rather than nepotism or favoritism.

Disadvantages of Weber's Bureaucratic Blueprint

Despite its advantages, Weber's bureaucratic blueprint also has several disadvantages. One of the major drawbacks is the rigid hierarchy that can stifle creativity and innovation. It can also lead to excessive bureaucracy, with too many layers of management and too much red tape. Additionally, bureaucracy can sometimes result in a loss of accountability, with workers becoming less motivated to take risks and make decisions because they feel they are not responsible for the outcomes.

Suggestions for Improvement and Challenges to Efficacy

One suggestion for improving Weber's bureaucratic blueprint is to implement a more flexible system that allows for greater creativity and innovation. This could be achieved by empowering workers to take more risks and make more decisions, while still maintaining a clear chain of command. Another suggestion is to simplify the bureaucracy by reducing the number of layers of management and streamlining procedures.

One challenge to the efficacy of these suggestions is resistance from workers who are used to the status quo and do not want to take on additional responsibilities. Another challenge is resistance from management, who may be concerned about losing control or reducing efficiency.

Pacific Island Countries Example

In many Pacific Island Countries, bureaucracy can be a serious challenge to economic development. The strict adherence to rules and procedures can stifle innovation and entrepreneurship. This has led to a lack of economic growth and employment opportunities. To address this, some countries have implemented more flexible systems that encourage innovation and entrepreneurship while still maintaining accountability and efficiency. For example, Samoa's Ministry of Commerce, Industry and Labour has implemented a "one-stop-shop" system that streamlines the process of starting a business.

The locomotive developed approximately 1341.176 horsepower.

To determine the speed of the train on a level ground, we need to consider the forces acting on the train. The resistance force on a level ground is equal to the train resistance, which is constant at 14 lb/ton, multiplied by the weight of the train. The weight of the train can be calculated by converting 1000 tons to pounds (1 ton = 2000 lb) and multiplying it by the gravitational acceleration (32.174 ft/s²).

Next, we can calculate the net force acting on the train by subtracting the resistance force from the force exerted by the locomotive, which is equal to the power divided by the velocity. Since the power exerted by the locomotive remains constant, we can use the power exerted while climbing the 1% grade.

Once we have the net force, we can use Newton's second law of motion (F = ma) to calculate the acceleration. Then, we can integrate the acceleration to find the velocity of the train on a level ground.

Finally, we can convert the velocity from ft/s to mi/hr to obtain the speed of the train on a level ground. The horsepower developed by the locomotive can be calculated using the formula: horsepower = (force × velocity) / 550, where force is in pounds and velocity is in ft/s.

Let us take the initial distance between car A and B as d₀. Let the time taken by car A to stop after it starts decelerating at a be t seconds. Now, the acceleration of car A = a (given), which is constant and negative (because it is decelerating).

Therefore, the velocity of car A after t seconds, vA

= uA + at

= va – at …(1) (where uA

= va is the initial velocity)The distance traveled by car A after t seconds, dA

The velocity of car B, vb, remains constant at vb throughout. So, the distance traveled by car B during this time t,

dB = vb × t …(3)

Now, we can use the equation of motion: for calculating the distance traveled by car A and B, respectively, where s = d₀ (initial distance between the cars) – d (distance between the cars at time t).Applying the equation to car A,

dA = (va + vA)t/2

= (va + va - at)t/2

= (2va - at)t/2

= va × t - (1/2)at² …(4) (using equation (1))

Applying the same equation to car B,

dB = (vb + vb)t/2

= vb × t …(5) (using equation (3))

We know that when car A stops, its velocity vA = 0.So, from equation (1), we get t = va/a. Substituting this value of t in equation (4) and (5), we get:dA = va²/2a …(6)and dB = vb × va/a …(7). Subtracting equation (7) from (6), we get the distance d between the cars at the instant car A stops.
