A) \[0.09{}^\circ \]
B) \[0.9{}^\circ \]
C) \[9{}^\circ \]
D) \[90{}^\circ \]
Correct Answer: A
Solution :
In figure,\[\theta \]is the angle of twist and\[\phi \]is the angle of shear. \[B{B}=OB\times \theta =AB\times \phi \] or \[\phi =\frac{OB\times \theta }{AB}\] \[=r\times \frac{\theta }{l}\] \[=\frac{2\times {{10}^{-3}}\times 45{}^\circ }{1}\] \[=0.09{}^\circ \]You need to login to perform this action.
