Question

Question 7 Considering the figure shown, the shear strain at point A relative to the x-yaxes is: 5 mm у 0.4 m 3 mm 0.3 m А 0.964 0 -0.964 0.0168 -0.0168 MacBook Air 80 GOS 000 F4 FS 97 # $ 4 A 3 % 5 & ON 7 8

Answer 1

sin $\theta$ = -5/300

$\theta$ = -0.964

$\therefore$ shear strain at A = -0.964 ( b)

shear strain at A negative.because the angle between the X and Y axes increases.shear strain at is taken as negative.

shear strain at A = - 0.964 degrees
