Geometry of Triangles and Angles Questions

Multiple choice

Lip clearance angle in a drill is at ________.

  1. 450

  2. 300

  3. 250

  4. 150
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The lip clearance angle of a drill bit is necessary to allow the cutting edge to penetrate the material. For standard drills, this angle is typically between 8 and 15 degrees.

Multiple choice

B.S.W. Thread has thread angle of _______.

  1. 370

  2. 450

  3. 550

  4. 600
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The British Standard Whitworth (BSW) thread is defined by a thread angle of 55 degrees, which distinguishes it from the 60-degree metric or Unified thread standards.

Multiple choice

The normal makes the angle with reflecting surface?

  1. 45°

  2. 60°

  3. 90°

  4. 75°
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The normal is defined as a line perpendicular to the reflecting surface at the point of incidence. Therefore, the angle between the normal and the surface is always 90 degrees.
