The same panel now has equal and opposite stresses at its two ends. Each boom receives

  • A.100 mm^2
  • B.300 mm^2
  • C.50 mm^2
  • D.150 mm^2

Answer: C

With a stress ratio of minus one the bracket becomes \( 2 - 1 = 1 \), so \( B = 50 \times 1 = 50 \) mm\( ^2 \). Only a sixth of the panel area is credited to each end, because much of the panel's load cancels within its own length.
