Mobile system: Rod ·OBC
Speed analysis:
Absolute motion: horizontal linear motion
Relative motion: linear motion along OBC
Suggested motion: circular motion centered on O.
OM=0.2m
Vc = 0.2 * 0.1= 0.02m/s
Va=0.02* root number 3 = 0.0346m/s.
Acceleration analysis:
It is suggested that the acceleration should be composed of tangential acceleration and normal acceleration of circular motion.
But because w is a constant, the tangential acceleration is zero.
So AE = 0.1* 0.1* 0.2 = 0.002.
Coriolis acceleration ac=2*0. 1*0.04=0.008.
Indirect calculation of implicated acceleration
Then according to the decomposition, a=0.0 12, horizontally to the left.
