Question:

The plastic distorts as shown by the dashed lines. (Figure 1)

The dimensions are {eq}L=500 mm, H=340 mm, d_1=3 mm, d_2=5 mm,d_3=14 mm, d_4=9 mm, d_5=1 mm, d_6=4 mm {/eq}.

Part A

Determine the shear strain {eq}\tau_{xy} {/eq} at corner A. Express your answer to three significant figures and include appropriate units.

Part B

Determine the shear strain {eq}\tau_{xy} {/eq} at corner B. Express your answer to three significant figures and include appropriate units.

Shear strain

The shear strain can be defined as the ratio of deformed to original dimensions. In the shear strain, the amount of deformation is perpendicular to a given line rather than parallel to it.

Answer and Explanation:

Given Data:

  • The length of the section is {eq}L = 500\;{\rm{mm}} {/eq}.
  • The height of the section is {eq}H = 340\;{\rm{mm}} {/eq}.
  • The deflection at...
