Final answer:
The projections of the thin horizontal plate are drawn based on the given spatial relations, resulting in a square in the top view and a line in the front view, representing the plate's orientation with respect to the Horizontal and Vertical Planes.
Step-by-step explanation:
The question pertains to the drawing of projections of a thin horizontal plate that has specific spatial relations to the Horizontal Plane (H.P.) and the Vertical Plane (V.P.). Given the dimensions of the plate and its orientation, the task is to represent these details in a two-dimensional view, as is common in engineering drawing or technical drafting.
The plate is parallel to the H.P. and perpendicular to the V.P., which means that in the top view or plan, the plate will appear in true shape. However, in the front view or elevation, the plate will appear as a line since it is perpendicular to the V.P. The given dimensions indicate the distances from the reference planes, and these details will be used to correctly position the projections in the drawing.
Given the spatial information, the steps to draw the projections will include:
- Starting with the top view, draw a 15 mm by 15 mm square to represent the true shape of the plate.
- Mark the distance of the plate above H.P. which is 10 mm in the front view, depicting it as a line since the plate is perpendicular to the V.P.
- Show the edge view of the plate, being a line 15 mm long, to indicate its position in front of the V.P.
The projection of the plate would be a representation of how it looks when viewed from the top and the front, according to the principles of orthographic projection.
