In Fig. a massive rod AB is held in horizontal position by two massless strings. If the string at B breaks and if the horizontal acceleration of centre of mass, vertical acceleration and angular acceleration of rod about the centre of mass are a_x,a_y respectively, then

In Fig. a massive rod AB is held in horizontal position by two massles

1.	In Fig. a massive rod AB is held in horizontal position by two massless strings. If the string at B breaks and if the horizontal acceleration of centre of mass, vertical acceleration and angular acceleration of rod about the centre of mass are a_x,a_y respectively, then
Answer» `2sqrt(3)a_(y)=SQRT(3)alphal+2a_(x)` `sqrt(3)_(y)=sqrt(3) alphal+a_(x)` `a_(y)=sqrt(3)alphal+2a_(x)` `2a_(y)=alphal+2sqrt(3)a_(x)` SOLUTION :Acceleration of POINT `A` along the string is ZERO. THEREFORE `a_(x)cos30^@-a_(y)cos60^@+(alphal)/2cos60^@=0`
