Object Details
- Baker, Richard P.
- Description
- This is a model of trapezoidal wedge, a surface with two triangular and three trapezoidal faces.Here two triangular faces and two trapezoidal faces of a wedge are shown in sheet metal. Two interior intersecting triangles that bisect the wedge and join opposite sides of the triangles are also shown in sheet metal - the trapezoidal face that would cover them is not shown. Wires rising from two edges of one of these bisecting triangles aand from the line of intersection of the bisectors form two sides and the diagonal of a parallelogram.
- Baker based this model on a diagram from a volume on dynamics by the German Eduard Study.
