Transcribed Image Text:# 2-13. Elongation after plate assembly
Certain application requires plates (1) and (2) to be attached to each other using glue, as indicated below. During fabrication
plate (1) was made 8 = 3 mm smaller than needed. Plate (1) was placed in an oven to increase its length so that it would
perfectly match the size of plate (2). The plates were then immediately glued together.
Plate (1) has stiffness x₁ = 40 × 10³ N/mm, plate (2) has stiffness k₂ = 19 x 10³ N/mm and L = 23 x 10² mm.
