4. When tolerance is given on one side of the basic, dimension, it is called, (a) Tolerance system (b) Allowance system, {c) Unilateral tolerance —_(d) Bilateral tolerance, , 2. The maximum clearance between hole 30-55) and, shaft 30-143 Is, (a) 0.164 mm (b)0.143 mm, , (c) 0.131 mm (d}0.110 mm, , 3. Limits of 50 mm hole is ES = + 0.025 and El = +, 0,002 mm. The maximum and minimum hole sizes, , will be :, , (a) Max. 50,02 mm; Min, 49.998 mm, , {b) Max. 50.025 mm ; Min. 50.002 mm, , (c) Max, 49,998 mm ; Min. 50.002 mm, , {d) Max. 49.990 mm; Min, 49.975 mm, 4. British standard limit system consists of, , {a) 21 classes of fits and 16 grades of tolerances, , {b) 12-classes of fits and 61 grades of tolerances, , (c) 16 classes of fits and 21 grades of tolerances, , (d) 61 classes of fits and 12 grades of tolerances, 5. Adimension is stated as @ 25 H; in a drawing. The, , lower [limit is, (a) 24.75 mm (b) 24.85 mm, (c) 25.00 mm (d) 25.021 mm, 6. Adimension is stated as 25 £0.02 mm in a drawing., What is the tolerance ?, {a) 25.00 mm (b) + 0.02 mm, {c) —0.02 mm (d) 0.04 mm, , 7. The difference between the maximum and minimum, sizes allowed in manufactured components is called, , (a) Clearance, , (b) Allowance, (¢) Tolerance (d) Limit, 8. The measured size of the dimension of a component, is called, {a) Basic size (b) Nominal size, (c) Allowed size (d) Actual size, , 9. Apinis fitted in a hole. The tolerance zone of the pin, is entirely above that of hole. The fit obtained will be, , (a) Clearance fit (b) Transition fit, (c) Interference fit (d) None of the above, 10. In the drawing the dimension of a shaft is shown, 4072288 mm. Which size of shaft is not within the, “©. tolerance ? ‘, - (a) 40.068 mm ~~, ~~ (¢) 40.000 mm, , », (b) 40,096 mm, (d) 39.998 mm, , 11., , 12., , 13., , 14,, , 15., , 16., , 17., , 18., , 19., , In the drawing the dimension of @ hole is sh,, 9.028 mm. Which size of the following is wa;, , 407:, , tolerance 7, (a) 40.000 mm (b) 40.010 mm, (c) 40,038 mm (d) 40.050 mm, , Interchangeability is normally applied for, (a) Repairing of parts (b) Mass production, (c) Single piece production(d) All the above, , Bilateral tolerance is fixed, (a) On upper side of the basic size, (b) On lower side of the basic size, (c) On any one side of the basic size, (d) On both sides (upper & lower) of the basic size, , Best example for driving fit is, (a) Ball bearing on the shaft, (b) Tyre on the rail wheel, (c) Pulley with key on the shaft, (d) Cart rim on the wooden wheel, , Best example for shrinkage fit is, (a) Cart rim on wooden rim, (b) Tyre on the rail wheel, (c) Tyre on the bicycle rim, {d) Flywheel on the shaft, , In hole basis system, (a) The size of the shaft is made constant, (b) The size of the hole is made constant, , (c) The permissible tolerances are given on the h, and the shaft, , (d) Allowance is given only on the hole, Tolerance Is given to the part size to, , (a) Increase the production, , (b) Decrease the production, , (c) Finish the components approximately, , (d) Produce the parts within the required permiss«, , size error, , As per BIS system of limits and fits, there are, — of tolerances represented by number symbt, , (a) 1TO1, (Tt ... to 1716, (b) 171... to 718, (c) ITO... to IT17, (d) IT01, ITO, IT1 to 16, Which of the following is not the correct methoo, expressing a fit under BIS system of limits and fis, {a) 45 H8/ 7 (b)45 97 / He
