REQUIRED: CONCLUSION AND RECOMMENDATION
FOR THE FOLLOWING SCENARIO: (should be 2
paragraphs with 7 sentences each)
We carried out a lab experiment on the stroop test.
According to the results of our analysis using Minitab
ANOVA, there was no error made when we were
carrying out the task.
here are the objectives of the task:
Students should be able to:
1. Understand how human brains process information.
2. Demonstrate compatibility and interference issues.
3. Determine how noise or interference affects
perception.

Write your answer on the space provided before each item number. Statement: The Philippine one-peso coin has a diameter of 23.0 mm at 25 room temperature. Assume that the coin is made up of steel.14. The increase in coin’s diameter when placed in boiling water is 0.0207 mm.15. The final length of coin when placed in boiling water is 23.207 mm.16. If the coin is heated at 42 degrees Celsius, then the increase in diameter is 0.0207 mm.17. If the initial temperature is doubled, then the increase in coin’s diameter when placed in boiling water is 0.0414 mm.

You are an engineer working on a project and your prototype has failed prematurely. You question whether or not a key component of the prototype was manufactured with the correct material. There are two way to check for the material properties. The first way is to have a material certification done to confirm the exact material composition. This will take some time. The second method to confirm the material properties is to make an ASTM test sample and test for the material properties. This tensile test was completed on a test sample with an initial diameter of .501” and an initial length of 2”. The Load-Deflection data for this tensile test is below. Use this data to answer the first set of questions on the Final Exam in eLearning. A. Determine the Ultimate Tensile Strength B. Determine the 0.2% Offset Yield Strength C. Determine the value of the Proportional Limit D. Determine the Modulus of Elasticity E. Determine the Strain at Yield F. Calculate %…

Questions (Wind Energy)
Q1:
The average wind velocity in a particular area is found to be 5.5m/s. It is proposed to
install a wind driven turbine with a blađe radius of 1.8m. The proposed design has an
interference factor of 0.21 and an axial force coefficient of 0.89, and a torque coefficient
of 0.8. Determine: a) The expected power output of the turbine. b) Thrust on the turbine.
c) Torque on the turbine. d) Rotational speed.
Q2:
Wind speed measurements at a particular location have been obtained with a view to the
possible installation of a wind turbine. The anemometer was located 12.5m above the
ground level. The average wind speed recorded during the testing was 9.2m/s. Estimate
the variation in wind speed across the 40 m diameter of the proposed turbine if the hub is
installed 30m above the ground.

Case Study: Paula’s Pain
Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months.
Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.)
Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons.
The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position…

At an intersection car B was traveling south and car A was traveling 30° north of east when they slammed into each other.
Upon investigation, it was found that after the crash, the two cars got stuck and skidded off at an angle of 10° north of east.
Each driver claimed that he was going at the speed limit of 50 km/h and that he tried to slow down, but couldn't avoid the
crash because the other driver was going a lot faster. The masses of cars A and B were 1500 kg and 1200 kg, respectively.

15) "Questions 13 and 14. If the fan moves 85 m3 of air per hour through the basement, this is the equivalent of a 50.03 cfm (cfm=cubic feet per minute) bathroom fan. Assuming the density of the air is 1.1123 kg/m3 and that 50% of the ventilated air makes contact with the walls for long enough to reach the wall temperature, using the psychrometric chart, how much moisture will be moved into or out of the basement in 24 hours (using conditions from questions 9, 10, 11, and 12) ? 14) What is the total weight (in kg) of the water vapour that is removed or added to the basement in 24 hours?
