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