Question
1)
Calculate the extension e of the hinge line of brachiopod shell using the following
formula.
Here, the original length of the undeformed brachiopod shell in cm is l,, the deformed
length of brachiopod shell in cm is /, ,
Measure the length of 1, and 1, of hinge line of undeformed and deformed brachiopod
using the metric ruler.
Substitute 5.5 cm for 1, and 6 cm for l.
e =
6-5.5
5.5
e = 0.091
2)
Calculate the angular shear y using the following formula.
w = 90° – 0
Here e is the angle subtended by the deformed perpendicular line with the hinge line.
Measure the angle 0 using the protractor in the deformed brachiopod.
Substitute 45° for e.
リ= 90°-0
= 90° - 45°
= 45°
Calculate the shear strain y using the following formula.
y = tan ự
Here y is the angular shear of the shell.
Substitute 45° for y.
y = tan y
= tan 45°
y = 1
