A) 2 mm
B) 225 mm
C) 2.50 mm
D) 3.00 mm
Correct Answer: B
Solution :
\[\omega =\frac{2\pi \times 300}{600}=10\pi \,\text{rad/s}\] \[\beta =\frac{\omega }{{{\omega }_{n}}}\,\frac{10\pi }{10}=\pi \] \[r=\frac{e{{\beta }^{2}}}{{{\beta }^{2}}-1}=\frac{2\times {{\pi }^{2}}}{{{\pi }^{2}}-1}=225\,\,mm\]You need to login to perform this action.
