Question

1. what is the upper limit of the dimension shown (in mm)? 30^{+2}_{-1} a. 29 mm b. 30 mm c. 32 mm d. 33 mm

Explanation:

Step1: Identify upper - limit concept

The notation $30^{+2}_{-1}$ means the nominal value is 30, the upper deviation is + 2 and the lower deviation is - 1.

Step2: Calculate upper - limit

To find the upper - limit, we add the upper deviation to the nominal value. So, $30 + 2=32$.

Answer:

C. 32 mm
