A hinged construction consists of three rhombus with the ratio
of sides (5: 3: 2). Vertex A3 moves in the horizontal direction with
velocity V. Velocity of A2 will be

A2.5 VB1.5VC0.8V

Show answer and solution▾

$u = \frac{dy}{dt} = - 16\sin\theta\frac{d\theta}{dt}$
$\Rightarrow u = \frac{4}{5}v = 0.8v$
