Question

For the planar mechanism of figure below, link 4 servers as slider support which is free to rotate about the z axis, but has point D kept stationary. Link 3 is a rigid member continuous over the rotational joint B. The lengths of the links 2 and 5 are respectively 3 cm and 7 cm, and the distance AB is 6 cm. The angles of the links 2, 3, and 5 with the positive horizontal are denoted as θ₂ , θ₃ and θ₅ , respectively. At the instant of consideration these angles θ₂ , θ₃ and θ₅ are respectively 100^o , 331.2^o and 70.1^o , while the distance AD is 10 cm. For the constant CCW angular speed of 2 rad/s of the link 2, determine:

(b) The velocity of the slider C,
