KEl6. Figure shows a mechanism. Body 5 is assumed to be homogeneous circular cylinder, and mass of the pulley 4 is uniformly distributed over its rim. The coefficient of sliding friction between bodies and the plane is f 0.1. The coefficient of stiffness of a spring is e. A force Fapplied to the mechanism depends on the displacement si of the body 1. The mechanism starts motion from rest, and at the...
You provided the following answer:
I don't understand why you ignore the vertical acceleration in
point D? Why are you assuming that aDt = 0?
I think there is a vertical acceleration in point D ...
Could you explain this?
