Question

D-3.


The velocity of end 'A' of rigid rod placed between two smooth vertical walls is 'u' along vertical


direction. Find out the velocity of end 'B' of that rod, rod always remains in contact with the vertical wall


and also find the velocity of centre of rod. Also find equation of path of centre of rod.

Answer 1

Answer:

Along the length of the rod the velocities should be same or the rod will break

and the velocity of B is always horizontal (net)

Velocity of A is vertical (net)

now take the components along the length and equate them

usinθ=vcosθ

utanθ=v
