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 the horizontal force on rod 1 by hinge A at this instant?
- \(\left(\frac{32-12 \sqrt{3}}{3 \sqrt{3}}\right) m \ell \alpha\)
- \(\left(\frac{16-2 \sqrt{3}}{\sqrt{3}}\right)\)
- \((14+2 \sqrt{3}) m \ell \alpha\)
- \(\sqrt{3} m \ell \alpha\)
Answer
(A) ( 32-12 3 3 3 ) m
