Q1: (Planar mechanism)
For the planar mechanism of figure below,
link 4 serves 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 0, 0,
and ,, respectively. At the instant of
consideration these angles 0, 0, and 0,
are respectively 100°, 331.2° and 70.1",
while the distance AD is 10 cm. For a
constant CCW angular speed of 2 rad/s of
the link 2, determine:
