A) \[{{V}_{A}}-{{V}_{O}}=\frac{B\omega {{l}^{2}}}{2}\]
B) \[{{V}_{O}}-{{V}_{C}}=\frac{7}{2}B\omega {{l}^{2}}\]
C) \[{{V}_{A}}-{{V}_{C}}=4B\omega {{l}^{2}}\]
D) \[{{V}_{C}}-{{V}_{O}}=\frac{9}{2}B\omega {{l}^{2}}\]
Correct Answer: C
Solution :
By using \[e=\frac{1}{2}B{{l}^{2}}\omega \] For part AO ; \[{{e}_{OA}}={{e}_{O}}-{{e}_{A}}=\frac{1}{2}B{{l}^{2}}\omega \] For part OC; \[{{e}_{OC}}={{e}_{O}}-{{e}_{C}}=\frac{1}{2}B{{(3l)}^{2}}\omega \] \[\therefore {{e}_{A}}-{{e}_{C}}=4\ B{{l}^{2}}\omega \]You need to login to perform this action.
