Question

draw the projections of a cylinder base 40mm diameter and axis 50mm long resting on the H. P. on their respective bases​

Answer 1

To draw the projections of the cylinder, we need to consider two views: the front view and the top view. In the front view, we draw the projection of the cylinder as a rectangle, and in the top view, we draw the projection of the cylinder as a circle.

To draw the front view, we draw a rectangle of height 50mm and width equal to the diameter of the cylinder, which is 40mm. We draw the rectangle in such a way that it represents the base of the cylinder resting on the ground or H.P.

To draw the top view, we draw a circle of diameter 40mm, which represents the circular base of the cylinder. We draw the circle directly above the center of the rectangle we drew in the front view.

By combining these two views, we can get a complete representation of the cylinder in 2D projections.
