A) \[50{{s}^{-2}}\]
B) \[25{{s}^{-2}}\]
C) \[2.5{{s}^{-2}}\]
D) \[6.25{{s}^{-2}}\]
Correct Answer: A
Solution :
[a] Torque =Fr Torque = \[I\alpha \] \[Fr=I\alpha \] \[25\times \frac{20}{100}=\frac{20}{2}\frac{20}{100}\frac{20}{100}\alpha \] \[\alpha =\frac{25}{2}=12.5{{s}^{-2}}\] MOI (I) Flywheel (disc)\[=\frac{M{{R}^{2}}}{2}\]You need to login to perform this action.
