A dimension is stated as Dia 25 H7 in a drawing. The lower limit is ?

5) A dimension is stated as 25 +/-0.02 mm in a drawing. What is the tolerance ?

Answer is:

0.04 mm

Explanation:

A dimension is stated as 25 +/-0.02 mm in a drawing. Then
Basic Size = 25.000 mm
Upper Tolerance = + 0.02 mm
Lower Tolerance = - 0.02 mm
Total Tolerance = 0.02 + 0.02 = 0.04 mm

6) The difference between the maximum and minimum sizes allowed in manufactured components is called :

Answer is:

Tolerance

Explanation:

8) A pin is fitted in a hole. The tolerance zone of the pin is entirely above of that hole. The fit obtained will be

Answer is:

Interference fit

Explanation:

If the tolerance zone of the pin is entirely above of that hole, then the fit obtained is called as interference fit.

Interference Fit Interference fit is defined as the fit established when a negative clearance exists between the sizes of the holes and the shaft. In Interference fit, the minimum permitted diameter of the shaft is larger than the maximum allowable diameter of the hole.

Examples for Interference Fit are: Bearing bushes, small end in the connecting rod.
