The rod AB, of length 1 m, shown in the figure is connected to two sliders at each end through pins. The sliders can slide along QP and QR. If the velocity VA of the slider at A is 2 m/s, the velocity of the midpoint of the rod at this instant is _____ m/s.

- None of these
Correct Option: A
Locate the I-centre for the link AB as shown in figure M is the mid point of AB
Given VA = 2 m/sec
| VA = IA.ω ⇒ ω = | |
| IA |
| VM = IM.ω = IM | = | .VA | ||
| IA | IA |
| = sin30°.VA = | .2 = 1 m/sec | |
| 2 |
