submission: 18/09/2023 Maximum marks: 5
Q.1 Define machine design.
Q.2 what is an adaptive design? Q.3 Suggest briefly the steps to be followed by a designer Q.4 Classify common engineering materials. Q.5: What are the advantages of malleable cast iron over white or grey cast iron? Q.6 A standard alloy steel used for making engineering components is 20Cr18 Ni2. State the composition of the steel. Q. 7 How are plain carbon steel designated? Q.8 Name two important copper alloys and give their typical compositions. Q.9: State at least 5 important mechanical properties of materials to be considered in machine design. Q.10 Define resilience and discuss its implication in the choice of materials in machine design. Q.11 what is meant by tolerance? How many types of tolerance is there? Q.12 what are the types fit? Describe the differences. Q.13. what are preferred numbers? Q, 14: Find out the numbers of the R5 basic series from 1 to 10. Q.15 Find out the numbers of R20/4(100… 1000) derived series. Q.16 A manufacturer is interested in starting a business with five different models of tractors ranging from 7.5 to 75 kW capacities. Specify power capacities of the models. There is an expansion plan to further increase the number of models from five to nine to fulfil the requirement of farmers. Specify the power capacities of the additional models. Q.17 it is required to standardize eleven shafts from 100 to 1000 mm diameter. Specify their diameters. Q.18 what do you understand by size of a product? Give examples. Q.19 what are the steps involved in design of a machine element? Q.20 how many basic series are used? How will you denote them? Q.21 what is a derived series? Q.22 Find out the numbers of R10 basic series from 1 to 10. Q.23 Find out the numbers of R20/3 (200…) derived series. Q.24 it is required to standardise load-carrying capacities of dumpers in a manufacturing unit. The maximum and minimum capacities of such dumpers are 40 and 630 kN, respectively. The company is interested in developing seven models in this range. Specify their load carrying capacities. Q.25 what is mild steel? What is the percentage of carbon in mild steel? Q.26 Define alloy steel. Name the various alloying elements in ‘alloy’ steels. Q.27 what is creep? 28. What are the types of plastics? Q.29 what is a thermoplastic? Give its examples Q.30 what is a thermosetting plastic? Give its examples
