For the position of the mechanism shown in Figure, find the velocity of the slider B for the given configuration if the velocity of the slider A is 3 m / s. Consider AB as a rigid link and is parallel to CD at this instant.

For the position of the mechanism shown in Figure, find the velocity of the slider B for the given configuration if the velocity of the slider A is 3 m / s. Consider AB as a rigid link and is parallel to CD at this instant. Correct Answer 3 m/s

Concept:

The velocity of a rigid rod will remain the same whether calculated by resolving the velocity vector of slider 'A' or slider 'B'  in a direction of a rigid rod i.e.

VA × cos 45° = VB × cos 45º = Velocity of a rigid rod (Vrd)

VA = VB = Vrd

Calculation:

Given:

Velocity of rigid rod = 3 m/s

∴ VA = VB = 3 m/s
