Question

A right circular cone, 40 mm base diameter and 60 mm long axis is resting on h.P. On one point of base circle such that its axis makes 450 inclination with h.P. And 400 inclination with v.P. Draw its projections.

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Refer the attachment

Construction:

• Draw XY line
• Draw TV as a circle of diameter 40 mm
• Divide the circle into 12 equal parts
• Take the projections of all point into FV
• Complete the FV taking axis length 60 mm
• Name the FV of cone on base as 1’ 2’ 3’….12’ and O’
• Take the vertical projections of all 12 points 1’, 2’, 3’, …12’ and apex points O’ in TV.
• Draw a smooth curve passing through all the 12 points
• Draw a line inclined at angle of 45° to XY line
• Mark point O at some convenient distance below XY line
