- PLEASE SOLVE THREE GIVEN SUB-PARTS i,ii,iii of the question. Accurate and exact. (i) State one mechanical material property and one non-mechanical material property that would be important in the design of a treadle. For each material property, state the units for that property and give a brief explanation of its importance in engineering terms to the design of the treadle. (ii) Propose a suitable material for the treadle. Explain your reasoning for your material selection, providing clear substantiating evidence of the materials suitability to the treadle. Your evidence should relate to the two material properties given as your answer to Part (i), but can also introduce other important factors. Provide sources of your evidence, which can be taken from EduPack or elsewhere. (iii) Explain why an Ashby chart might be useful to help selecting an appropriate material for the treadle.arrow_forwardThe new line of go-karts will have a two-stroke internal combustion engine. The engine generates 35 horsepower at a mean speed of 2000 rpm. The biggest variation in energy per revolution, according to dynamic analysis, is 25% of the mean energy. Design a flywheel to go along with this engine such that the maximum coefficient of speed fluctuation is 0.01. Your design should include all necessary details, such as the design calculations, the appropriate material, detailed dimensions, and manufacturing procedures. Note: As a design problem, there is more than one acceptable solution. One design, though, might be superior to others.arrow_forwardDifferentiate Between Gear Hobbing And Gear Shaping With Reference To Various Relative Motions And Applications?arrow_forward
- You have been tasked with designing a set of gears made from a material with a Brinell hardness (Hg) of 201 MPa. Previously your company has produced gears with a commercially polished surface finish, but your boss is interested in how much the bending strength would be decreased if a machined surface was used instead, with all other factors kept constant. Considering the surface factor figure and the AGMA equation for bending strength presented below, approximately what percentage decrease in bending strength (S,) would we expect to see changing from a commercial polished finish to machined surfaces? Hardness (Hp) 120 160 200 240 280 320 360 400 440 480 520 1.0 `Mirror-polished 0.9 Fine-ground or commercially polished 0.8 - Machined or cold-drawn 0.7 0.6 0.5 Hot-rolled 0.4 0.3 As forged 0.2 Corroded in tap water 0.1 Corroded in salt water 60 80 100 120 140 160 180 200 220 240 260 Tensile strength S, (ksi) St Sn = S'nCskrk¢kms O 28% O 20% O 23% O 7% Surface factor C,arrow_forwardA transmission shaft supporting a helical gear B and an overhung bevel gear D is shown in Fig. 9.10. The shaft is mounted on two bearings, A and C. The pitch circle diameter of the helical gear is 450 mm and the diameter of the bevel gear at the forces is 450 mm. Power is transmitted from the helical gear to the bevel gear. The gears are keyed to the shaft. The material of the shaft is steel 45C8 (Sut = 600 and Syt = 380 N/ mm”). The factors ky and k, of ASME code are 2.0 and 1.5 respectively. Determine the shaft diameter using the ASME code.arrow_forwardWith proper reasoning and neat sketches derive the Buckingham equation for spur gear so that pitting failure does not take place.arrow_forward
- Selasi wants a shaft of 5/8 inches diameter to be used in his design project of which he is considering a design factor of 3. He hopes to get the same shaft size or 11/16 inch diameter shaft in the market for his design. So he decided to send his apprentice, Amuzu to the market. Unfortunately, when Amuzu went to the market, there were 1⁄2 inch, 9/16 inch, 3⁄4 inch, and 7/8 inch sizes available in the first shop. Amuzu decided to buy the nearest shaft size in the first shop instead of checking in the other shops where he could have gotten either 5/8 inch or 11/16 inch sizes.a. Discuss the consequences Selasi would incur in his design project if Amuzu had bought 9/16 inch size shaft. b. Discuss the consequences Selasi would incur in his design project if Amuzu had bought 3⁄4 inch size shaft.arrow_forwardPlease don't provide handwritten solution .... 5.2 Sketch the following thread profiles for a nominal diameter of 25 mm and pitch 3 mm and give their applications: (a) BSW thread, (b) Buttress thread (c) Square thread, (d) ACME thread and (e) Worm threadarrow_forwardAs an engineer you are asked to choose 1 component from what you studied ( Screw, rolling bearing, Sliding Bearing, key, or shaft). 1.
