Step 1
Draw the plan of sphere A.
Answer
To draw the plan of sphere A, start by identifying the center of the sphere. Since sphere A is the topmost sphere in the stack, depict it as a circle. The radius should be consistent with the diameter indicated in the elevation view. Label the center point of this circle as 'A'.
Step 2
Draw the elevation of the sphere B when it has been moved into position C.
Answer
Begin the elevation by indicating the new position of sphere B at point C. The projection lines from point C should be drawn extended down to the square base to identify its new base position. Draw the outline of sphere B below its center at the new location while ensuring it makes contact with sphere A at point P.
Step 3
Draw the plan of sphere B in its new position and complete the drawing of the structure.
Answer
In the plan view, illustrate sphere B at the new position derived from the elevation drawing. Mark the center as 'B', and draw its corresponding circular outline. Once sphere B is represented, ensure that the lines showing the contacts between all spheres and the square base are accurately drawn. Finally, complete the drawing by ensuring that all projections are marked clearly and the overall structure appears cohesive.
