Consider a structure including the horizontal beam AB hinged to the wall at point A and supported by steel bar at point B, as shown. The length of the beam is L = 3.7 m and its weight is W = 450 N. The length of the steel bar is h = 2.5 m and its radius is r = 1.2 cm. The elastic modulus of the steel bar is E = 200 GPa. _(a) Draw the free body diagram (FBD) of the horizontal beam AB ; (b) Draw the FBD of the steel bar;_Determine (c) the magnitude of the reaction force, RA, at point A; (d) the tensile stress, o, exerted by the beam on the steel bar; (e) the tensile strain, ɛ, developed in the steel bar B

Project 7: In this project you were assigned to explore your mechanical design and system capabilities. Your manger asked you to prepare a technical research report to evaluate the effects of misalignment of shafts and the measures that are taken to prevent problems from occurring. The hiring committee asked you to deliver a short report showing your evaluation (no more than 600 words).

I asked for problems 6 and 7 to be answered, but I did not get a properly structured answered as the example shows on problem number 1. Here is the link to the questions I already had answered, could you please rewrite the answer so its properly answered as the example shows (Problem 1)?   https://www.bartleby.com/questions-and-answers/it-vivch-print-reading-for-industry-228-class-date-name-review-activity-112-for-each-local-note-or-c/cadc3f7b-2c2f-4471-842b-5a84bf505857

Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator.  This is Jeff's first position after completing his engineering degree.  He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job. Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace.  They have never had an individual dedicated to this task full-time.  They will implement his recommendations if he can justify them. As Jeff begins to get familiar with the operations, he spends considerable time on the production floor.  He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum.  They also use this liquid to clean residue from their skin.  They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke. In talking with the workers, Jeff learns of some of their concerns.  Several people mention…

1) Prof. K. climbed a wall and is now stuck and hungry. One of her ME 242 students saw this opportunity to test one of their pulley mechanisms to lift some pizza boxes for Prof. K. If the student is pulling the free end with a velocity of 2.75 ft/s. a) What is the mechanical advantage between the student and the pizza boxes? Hint: The link between pulleys 1 and 4 is rigid (meaning that they must move together. This is the key to solving this problem! b) What is the velocity of the pizza boxes? Be sure to indicate which direction it is moving. [Ans. to check: 1.375 ft/s] PizzA 49°F Sunny O 4x 99+ P Type here to search End PgUp PgDn PrtScn Home

Task 1 You have been moved into the laboratory for the fluid testing for hydraulic devices and a considerable amount of research has been carried out in an attempt to understand the exact nature of the temperature variation of viscosity. Inspect the table given below and note the relative values of viscosity for each Newtonian fluid at a given temperature. Compare the results of a viscosity test and comment on why the viscosity of ethanol and water is considerably lower than motor oil and explain any discrepancies. Temperature [°C] Water (μ) Ethanol (μ) Motor oil (SAE 15W-40) (μ) [mPa s]/ cP [mPa s]/ cP [mPa s]/ cP 10 1.30600 1.4475 582.95 20 1.00160 1.1841 287.23 30 0.79722 0.9764 155.31 40 0.65272 0.8151 91.057 50 0.54650 0.694 57.172 60 0.46602 0.6034 38.071 70 0.40353 0.5231 26.576 80 0.35404 0.01043 19.358 90 0.31417 0.01074 14.588 100 0.28158 0.1104 11.316 To complete this task, it is required to evaluate the effects of shear force on three Newtonian and three non-Newtonian…
