Question

A bone sample is submitted to a uni-axial compression test instrumented with 4 gauges (45 degrees between gauges A and B, 45 degrees between gauges B and C, and 30 degrees between gauges C and D). The data measured is:

Strain values:

E 0.0104
  $\epsilon _b = -0.0384$       $\epsilon _c = -0.0229$

Angle values between gauges:

$\theta AB = \theta BC = 45^o$   $\theta CD = 30^o$

What should the strain value for D ($\epsilon _d$) be is the error must be less than 1%.

In other words, what is $\epsilon _d$ for an error of less than 1%?
