Question

A 90 mm long is parallel to the 25 mm in the front of the vp its one end is in the hp while the other is 50mm above the hp draw its projection and the find its inclination with the hp

Answer 1

The inclination is 33.748 degree from Horizontal

Given:

Front Projection of 90 mm long line

50mm above the hp

To find:

for Angle Ф ,

Sin Ф= 50/90,

Ф= 33.748

Length of line in Top View = (90 COS 33.748°= 90* 0.83)

= 74.83 mm
