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.
