## Homework Statement

A bead C can move freely on a horizontal rod. The bead is connected by blocks B and D by a string as shown in the figure. If the velocity of B is v. Find the velocity of block D.

## Homework Equations

As the string is inextensible the velocity of the string along the length is const.

## The Attempt at a Solution

The doubt I have is that, the following should be true

[tex]v_c\ =\ v_b.cos53°\ \ \ \ ...(1)[/tex]

But in the solution from the book I get that

[tex]v_b\ =\ v_c.cos53°\ \ \ \ ...(2)[/tex]

I used relation 1 and got wrong results, I'm just confused how do we get relation 2.

Kindly help me out.

Thanks for your time
