aB=? with unit of i m/s2

To be able to use the equation for relative acceleration
between two points to find unknown linear accelerations and
angular accelerations of connected bodies.
Member ABC is controlled using a rack and pinion, which is
connected at B. (The rack is the long, horizontal gear.) The
rack can only move horizontally and the pinion does not
translate. A block in a sleeve is connected at A and allows
movement only in the vertical direction. Member ABC has a
total length of 2.10 m and the distance between A and B is
1.25 m. When member ABC forms an angle of 0 = 33.0°
with the rack, the acceleration of B is ag = 1.35 m/s? and
the velocity of the block attached at A is vA = 2.55 m/s in
the direction shown. Positive angular velocity and acceleratior
are in the counterclockwise direction.(Figure 1)
ag
Find the acceleration of B when the acceleration of C is ac = 4.45 i+1.36 j m/s? and the acceleration of A
is a4 = -2.00 j m/s . Member ABC makes an angle of 0 = 19.0° at the instant considered.
