Topics: Statics of Rigid Bodies, Equilibrium of Rigid Bodies, Equilibrium in Two Dimensions, etc. I will rate you with “LIKE/UPVOTE," if it is COMPLETE STEP-BY-STEP SOLUTION. If it is INCOMPLETE SOLUTION and there are SHORTCUTS OF SOLUTION, I will rate you with “DISLIKE/DOWNVOTE.” Thank you for your help. PS: If you have answered this already, don’t answer it again; give chance to other experts to answer it. I want to verify if all of you will arrive in the same final answer; thats why I ask it multiple times.
THIS IS NOT A COMPLETE QUESTION, IT JUST NEEDS TO HAVE THE STEPS IN THIS WAY. (PLEASE DON'T SEND ME A CHEGG ANSWER! I HAVE A CHEGG ACCOUNT. I SENT THIS QUESTION CHEGG AND I DON'T WANNA TAKE SAME ANSWER LIKE THAT! PLEASE JUST SOLVE ON YOURSELF OR LEAVE PLEASE. Fluid Mechanics question.)
Learning Goal: A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids.An object is made from a uniform piece of sheet metal. The object has dimensions of a = 1.45 ft, where a is the diameter of the semi-circle, b = 3.24 ft, and c = 2.10 ft. A hole with diameter d = 0.500 ft is centered at (1.13, 0.725).

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
Energy and system size calculation TEQ assessment (4.1) Design a question to calculate the cooling load for the building you selected for You will define at least FOUR types of heat gain in that building (or the floor you are working on or you are familiar with). The indoor temperature is set as 75 F, and you can assume the outdoor temperature based on the location of your building in the summer and any other numbers needed to resolve this question. (4.2) Calculate the corresponding cooling load for the question you designed above. For all the details as well as the final answer that this question is asking for, clearly indicate the unit for each piece of information. In a word, you will design a question for your building about cooling load calculation. Assumptions and/or supporting drawings/figures/tables are allowed and encouraged. You can decide the level of detail for this question, e.g., the more details and the more accurate information, the more accurate and realistic your…

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the Ti-6Al-4V…
