Multiple Choice Question (MCQ)

Question: Which operation is used to increase the diameter of work slightly to get a press fit?
A. Knurling
B. Turning
C. Punching
D. Grooving
Correct Answer: Knurling
Explanation

To solve for x in the equation (x + 2) / 2 = 19, you can first multiply both sides of the equation by 2 to get rid of the fraction.

2 * (x + 2) / 2 = 2 * 19 x + 2 = 38

Then, you can subtract 2 from both sides to solve for x x = 38 - 2 x = 36

So the value of x that satisfies the equation (x + 2) / 2 = 19 is 36.
