A 2024-T3 aluminum bar has rectangular cross section dimensions of 2" x 0.5". The length of the column is 9.0 inches.

A) Calculate the transition slenderness ratio (Sr)_D for this column. [Answer should be 69.9]

B) Calculate the slenderness ratio for your assigned column length. [Answer should be 62]

C) Calculate the maximum unit load (P_cr/A) for the bar. Indicate whether the column is a Johnson or Euler column. [Numerical answer should be 25296 psi but I don't know Johnson or Euler]

Please show steps for all parts.

Visit a local auto repair operation like walmart or peboys and observe battery replacement, oil change, jack operation, and general safety on site.

Develop a inspection form to assess a work facility.

Develop a inspection form targeting specific workplace hazards associated with an activity and equipment.

Coordinate with a work organization to conduct a general inspection of a work facility or work unit and conduct a detailed inspection of a specific workplace activity and related equipment.

Develop a report with inspection results, including a risk assessment of hazards identified and recommendations for hazard control if deficiencies are noted.

Coordinate with a work organization to complete a job safety analysis of a work task. The write-up should summarize the analysis and a completed analysis form should be included in the paper submission.

The College of Business and Public Administration at Benton University has a copy machine on each floor for faculty use. Heavy use of the five copy machines causes frequent failures. Maintenance records show that a machine fails every 2.5 days (or A = 0.40 failure/day). The college has a maintenance contract with the authorized dealer of the copy machines. Because the copy machines fail so frequently, the dealer has assigned one person to the college to repair them. The person can repair an average of 2.5 machines per day. Using the finite-source model, answer the following questions:

A) What is the average utilization of the maintenance per person

B) On average, how many copy machines are being repaired or waiting to be repaired

C) What is the average time spent by a copy machine in the repair system (waiting and being repaired)?

How can you engineer human emotion in artificial intelligence? Do not copy and paste from other websites without giving credit or putting things in quotes. For example, don't say it is possible to engineer human emotion by using engineering principles. What kind of engineering principles? How does engineering even come into the picture?

Explain the process of multi-stage compression with inter-eco-ling. is advantage gained by incorporating this process into a gas cycle? How does adding an inter-cooler this

For internal combustion engines found that the cycle thermal cffciency would increase with an increase in compression ratio of the cycle. Discuss the factors that limit us in taking advantage of this fact and this explains the higher efficiencies of compression ignition engines

Construct a sketch to show the working of an air handler of the blow-through type with cooling and
heating coils in series? Clearly label all parts and components and briefly explain its working?

Air enters the compressor of a regenerative air-standard Brayton cycle with a volumetric flow rate of 100 m3/s at 0.8 bar, 280 K. The compressor pressure ratio is 20, and the maximum cycle temperature is 1800 K. For the compressor, the isentropic efficiency is 92% and for the turbine the isentropic efficiency is 95%. For a regenerator effectiveness of 86%, determine: (a) the net power developed, in MW. (b) the rate of heat addition in the combustor, in MW. (c) the percent thermal efficiency of the cycle.

A mud logger places a sample of calcium carbide in the drillstring when a connection is made. The calcium carbide reacts with the mud to form acetylene gas. The acetylene gas is detected by a gas detector at the shale shaker after pumping 4, 500 strokes. The drill string is composed of 9, 500 ft of 5-in, 19.5-lbm/ft drill pipe and 500 ft of drill collars having an ID of 2.875 in. The pump is a double acting duplex pump with 6 in liners, 2-in rods, and 14 in strokes and operates in a volumetric efficiency of 80%.

a.Estimate the pump cycle required to move the gas from the surface to the bit.

b.Estimate the number of pump cycles required to move the gas from the bit to the shale shaker.

c.If the penetration rate of the bit is 20 ft/hr and the pump speed is 60 cycle/min, how many feet are drilled by the bit before the formation gas expelled from the rock destroyed by the bit travels from the bit from the surface?

The displacement volume of an internal combustion engine is 2.19 liters. The processes within each cylinder of the engine are modeled as an air-standard Diesel cycle with a cutoff ratio of 2.5. The state of the air at the beginning of compression is fixed by p1 = 1.6 bar, T1 = 325 K and V1 = 2.36 liters. If the cycle is executed 2100 times per min, determine: a) the compression ratio, b) the net work per cycle, in kJ, c) the maximum temperature, in K, d) the power developed by the engine, in kW, e) and the thermal efficiency.
