Two rods 1 and 2 are released from rest as shown in figure.
Given: l1 = 4l, m1 = 2m, l2 = 2l and m2 = m.
There is no friction between the two rods. If a be the angular
acceleration of rod 1 just after the rods are released. Then:
What is initial angular acceleration of rod 2 in terms of the given parameters in the question?
- \(\left[\frac{2 \sqrt{3} g}{2 \ell}+2 \sqrt{3} \alpha\right]\)
- \(\left[\frac{3 \sqrt{3} g}{\ell}-\sqrt{3} \alpha\right]\)
- \(\left[\frac{6 \sqrt{3} g}{8 \ell}+5 \sqrt{3} \alpha\right]\)
- \(\left[\frac{3 \sqrt{3} g}{8 \ell}-\frac{8}{\sqrt{3}} \alpha\right]\)
Answer
(D) [ 3 3 g 8 - 8 3 ]
