1. A line AB 65 mm long has its end A 25
mm above HP and 30 mm in front of VP. The other end is 45 mm above HP and 50 mm
in front of VP. Draw the projections and determine its inclinations.
2. A line AB 60 mm long has one of its
extremities 20 mm in front of VP and 15 mm above the HP. The line is inclined
at 250 to HP and 400 to VP. Draw its top and front views.
Find the apparent inclinations and the length of the views.
3. The top view of a line PQ 75 mm long
measures 50 mm and the front view measures 60 mm. The end P is 30 mm above the
HP and 15mm in front of VP. Draw the projections of the line and find its true
inclinations with HP and VP. Find the distance between the end projectors.
4. The end A of a line AB is in HP and
25 mm in front of VP. The end B is in VP and 50 mm above HP. The distance
between the end projectors when measured parallel to the line of intersection
of HP & VP is 65 mm. Draw the projections of the line AB and determine its
true length and true inclinations with HP & VP.
5. A
straight line AB measuring 80 mm long has the end A in the HP and 25 mm in
front of the VP. Its midpoint M is 25 mm above the HP and 40 mm in front of the
VP. Draw the views of the line and determine the inclination of the line with
HP and VP and also find the distance between end projectors.
6. A straight line PQ inclined at 400 to VP has pq = 60 mm and p’q’ = 50 mm. The end P is both in HP and VP, and 40 mm to the right of LPP.
a. Draw the projections of the straight line PQ.
b. Find the true length and true inclination with HP.
c. Draw the profile view of the straight line.
d. Find the position of the end Q from VP and HP.
