Question

14 Second angle projection is not used because
(A) Plan is above xy
(B) both views overlap each other
(C) elevation is above xy
(D) views are small in size​

Answer 1

Answer:

overlapping each other.

Step-by-step explanation:

As per rule of projection when horizontal plane is rotated 90 degree in clockwise direction, top and front view will overlap. Overlapping projection views create confusion in the drawing. Therefore 2nd angle projection system is not used.

Answer 2

Second angle projection is not used because both the views overlap each other :

Explanation:

• According to the rule of projection when horizontal plane  rotates by  90° withinside the clockwise  direction, the top and the the front views overlaps.
• And then this overlapped projection view creates a complexity or confusion within the drawing.
• This is the reason why the second angle projection system not used.
• Due to the reason of overlapping the 2nd angle projection system is not used to draw engineering drawings.

Answer - The option (B) both views overlap each other is the correct option.
