The given construction as shown in Fig. ...

The given construction as shown in Fig. 2 (HT) .3, consists of two rhombus with the ration ` 3: 2, The vetex `A_2` moves In the horizontal direction with a velocity ` v`. Find the velocity of ` A_1`.

Text Solution

Verified by Experts

The horizontal velocity of vetex ` A_0` is zero. Let` l_1` and ` l_2` be the lengths of rhombus along the horizontal direction. Given, ` l_1/l_2 = 3/2`
If `v_(A_1), V_(A_2)` are the velocity of vertex ` A_1 ` and ` A_2` respectively ,
then, ` u_(A_1)/v_(A_2) = 3/( 3 + 2) = 3/5`.
:. ` v_(A_1) = 3 k` and ` v_(A_2)= 5 k`
Given, ` v_(A_2) = 5 k =v` or ` k= v/5 ` :. v_(A_1) = 3 k = 3 xx v/5 0.v`.
