1.Interchangeability is the ability of the produced parts to Change any part within permitted limits of clearances Change part beyond any limits of clearances Produce mating parts within required limits of clearance Produce mating parts at any limits to interchange with other 'a' and 'c' 2.Limit system results in Large amount of rejected parts out of the required clearance Saving large amount of parts by production within the required clearance Assures the mating of parts Heavy cost to implement rules 'b' and 'c' 3.Hole and shaft sizes will interfere the interchangeability of the mating parts if The difference between basic size and shaft size exceed the proposed clearance The difference between basic size and hub size exceed the proposed clearance The difference between basic size and actual size exceed the proposed clearance The difference between basic size & nominal size exceed the proposed clearance The difference between basic size and tolerance size exceed the proposed clearance 4.Difference between upper and lower limit of a part is called Clearance Allowance Basic size Actual size Tolerance 5.Difference between actual sizes of mating parts is called Clearance Allowance Basic size Nominal size tolerance
6.if the size of shaft is 18+0.5mm and size of hub is 19+1.0mm then the Fit is a) Clearance fit b) Interference fit c) Transition fit d) Anyone of the above e) Sizes are very different so no fit will occur Zif the size of shaft is 200.00mm and size of hub is 21+0.9mm then the Fit is a) clearance fit b) Interference fit c) Transition fit d) Anyone of the above e) Sizes are very different so no fit will occur 8.if the size of shaft is 50+0.5mm and size of hub is 49+0.4mm then the Fit is -0.5 a) clearance fit b) interference fit
8.if the size of shaft is [50] (-0.5)^(+0.5)mm and size of hub is [49] (-0.5)^(+0.4)mm then the Fit is clearance fit interference fit transition fit anyone of the above sizes are very different so no fit will occur 9.Which welding process is suitable for fast rate or for mass production Gas welding Arc welding Thermit welding Anyone above 10. Which one is corner joint from the given figure? 'a' 'b' 'c' 'a' and 'c' both 5:01 pm
