A1-41: DRAWING PUZZLE - INTERSECTING RODS

a1-41b

  • ID Code: A1-41
  • Purpose: Visualize three-dimensional figures
  • Description:

    What solid object has circles as its front and side views, as shown below, but its top view is not a circle?

    This demonstration helps students to learn about a common pitfall in translating between two-dimensional cross-sections and projections in mechanical drawings, and the three-dimensional objects they represent.

    This can also be useful when discussion ideas of perspective and imaging.
