System of Pulley and Constraint Relation - String constraint

Laws Of Motion - Problems On Constraint Relations

In given system a_(1) and a_(2) are the accelerations of blocks 1 and 2. Then constraint relation is

Make the constraint relation between a_(1),a_(2) and a_(3)

In the arrangement of three block as shown in fig. the string is inextensible. If the direction of accelerations are as shown in the figure, then determine the constraint relation.

Consider the situation shown in figure-l.76 (a) Find the constraint relation for velocities of blocks A and B.
