Question
In the position shown, the angular velocity and
angular acceleration of bar AB are wAB = 3 rad/s clockwise and aAB =
12 rad/s? counter-clockwise.
4.1 consider the direction of the absolute velocities at point C and B, locate
the Instantaneous Centre, and figure out wBc
4.2 by inspection, find out the direction and magnitude of the acceleration
vector (consists of a normal and a tangential component) at point B. Express
aB/o using the i, j base vector.
4.3 use equations ac/o = aß/o + ac/B and
acjo = Aß/o + aßc × rc/B + WBc × (@Bc × rc/B ), calculate aBc and acjo
