mination Paper 2016 MECH 12060 Page 4. For this question, you will need to refer to Figure 3 (on Page 6), which shows a part of a drawing of the front elevation of a bearing bracket. Which of the following statements is not true? a. The base and hole in the bracket are machined. b. The outline shape of bracket is probably produced by millin the c. The full drawing of the bracket contains a sectional view. d. The hole in the bracket is probably finished using a reaming process.

Solution

The questions is referred from the diagram shown.

The answers are explained as below:

a) TRUE

The base & hole in the bracket are machined through drilling & milling operations. The surface processing operations are useful for high precision parts.

b) FALSE

The outline shape of bracket is not produced by milling because the outline shape is fillet having a specified radius. Milling operations are useful for flat surfaces on machine parts.

c) TRUE

Full drawing of the bracket contains a sectional view through center & the dotted line A-A is depicting the presence of section.

d) TRUE

The holes are generally finished through reaming operations.

So, the option is b) FALSE.
