Question

Part 1. Select an object from your everyday life that GDT could be applied to. Attach a

graphic image of it (a photograph, a scanned sketch or a computer generated drawing) in JPEG format here.

Part 2. Identify two primary functions of this part (e.g. must assemble to other part(s), smooth rolling, must not wobble when placed on a flat surface). Briefly describe the functions.

Part 3. Assign a minimum of two geometric tolerances (including at least one that requires the use of datums) to the part to ensure that the part will successfully achieve its two primary function. Assign datums as necessary. Create a sketch or drawing to show where the datums and tolerances will be applied. Assign values for the tolerances, however you will not be marked on the magnitude of the tolerances.

Part 4. Briefly describe how the part would be inspected to verify that it meets the geometric tolerances.

Question

Please provide some ideas for 300 words essay!

According to one historian, R.S. Westfall, the mechanical

philosophy that posited a physical world of little corpuscles or atoms in motion was startling in its bleakness—but admirably contrived for the purposes of modern science. The belief in a material substratum devoid of secondary properties (colours, sounds, tastes etc.) appealed to most of the leading seventeenth-century natural philosophers, notably Galileo, Descartes, Boyle, and Newton. Yet, this microscopic world was beyond the reach of human observation. Why was the mechanical philosophy so deeply rooted and so widespread? In what respects did it reinforce some of the new scientific theories and methods, in astronomy, physics, and chemistry?

Question

A 3 kg mass (m) is attached to a stationary ceiling through a spring with stiffness ( K ) and damper. A force is

applied to create oscillating motion. This force is applied until time equals zero. After a short interval after time, a data recorder measures the mass’s position. This position data is plotted as a red line in the diagram below. Two of the maximum displacement positions are measured at 35 and 20 mm, respectively.

a) If the time interval between the +35 and the +22 mm displacements is 0.7 sec, determine the value of K.

b) Determine the unknown (??) displacement amplitude.

Question

A closed tank contains 2 kg of saturated liquid water, initially at 80°C (state 1). Heat transfer occurs and the

tank is allowed to expand such that the liquid-vapor mixture remains at 80°C. At some point during this process (state i for intermediate) the tank becomes rigid, after which more heat is added until the tank contains only saturated vapor with v = 2.045 m3 /kg (state 2). (a) Sketch this process on P-v and T-v diagrams. (b) Find P, T, and v for all three states, and summarize them in a table. (c) Determine the heat transfer into the system during this process, Q12.

Question

A 12 Horsepower motor has a speed of n=1790 rpm and drives a fan at 250 RPM. The sheave mounted on the motor has

4.2 pitch diameter. The service factor is 1.1 and the design factor is to be 1.0. The motor size is such that the distance C must be no less than 45 in. Fully specify an appropriate v-be drive and estimate life in both passes and hours. Choose a solution that keeps center distance as close to 45 in as possible without going under. Be sure to identify all work.

SP18

– The boilers at Purdue’s Wade Utility Plant

produce steam at 600 psig (~4.2 MPa)

Question

SP18 – The boilers at Purdue’s Wade Utility Plant produce steam at 600 psig (~4.2 MPa)

and

825 F (~440°C). After partial expansion through the turbine generator, steam at 15 psig (~205

kPa) and 350 F (~175°C) and at 125 psig (~960 kPa) and 530 F (~275°C) is bled off and routed to campus for heating and processing.

[https://stemedhub.org/resources/772/download/What_Would_It_Take_To_Power_Purdue_University.pdf]

Assume that one of the boilers feeds one of the turbines 120,000 lb/hr of steam. This is about 15 kg/s. Also assume that 15% of the ~4 MPa/440°C flow is bled off to the ~1000 kPa/~280°C line and an additional 10% is bled off to the ~200 kPa/~160°C line. The remaining 75% exits the turbine at a pressure of 0.1 bar and a quality of 90%.

What is the turbine power rate? Report your answer in MW.

A rigid tank is divided into two equal parts by a partition. One part of the tank contains 3.5 kg of compressed

liquid water at 400 kPa and 600C while the other part is evacuated. The partition is now removed, and the water expands to fill the entire tank. Determine the entropy change of water during this process, if the final pressure in the tank if 60 kPa

Hi I just want someone to correct any grammars mistakes I have made in my personal statement I am using to apply

Question

hi I just want someone to correct any grammars mistakes I have made in my personal statement I am using to apply

to to college. It should be quick and easy since I have already passed by several people.

My introduction to Mechanical Engineering came about through my fascination with Astronomy and realising that astronomical instruments are designed by Mechanical Engineers. The workings of rocket engines and robots added fuel to my enthusiasm to learn about design and manufacturing technologies. I believe mechanical engineering is the most important work a person can be involved in, shaping the future using new technologies such as 3D printing and designing machines and maintaining the ones we depend on so much. I am excited to develop my physics and maths knowledge, because even though it is interesting to learn about Pascal’s Principle, using it to design a hydraulic cylinder and calculate the outcome, is what matters the most.

I want to go into the Aerospace Industry and hope to contribute to the civilian space travel sector, where Virgin Air and Blue Origin have made pioneering starts. I spend a lot of time on simulation software, like KERBAL where I design and simulate machines in virtual reality which obey the physical and mechanical laws. I am exited to learn how to use professional simulation tools such CAD so I can design with 100% accuracy to the real world. I enjoy problem-solving and always try to improve my technique by solving puzzles from books such as My Best Mathematical and Logic Puzzles by Martin Garden. I also have improved my studying and note taking techniques and continue to do so by taking online courses.

I recently found the Institution of Mechanical Engineers, and I have booked to attend lectures to help me view the industry from a more business oriented perspective and to hear others experience and advice, and begin networking early. I hope to join the course and if you give me a chance I will take full advantage of the course and extracurricular activities. I assure you that I will work hard and shine as one of your top students, trying to fulfill my aim and goal of being a Mechanical Engineer of the future.
