@engineers_feed When the circle A (radius R) makes one full rotation, the center of it, is moving on a circle with center the center of B circle (radius 4R). So : 2πR=4Rφ=> N2πR=4R 2π (for a full rotation)=> N=4
@engineers_feed Newton second law for thw pulley: FR-5g(moon)R=Iα.
1. if the pulley has I=0, the block does not moving (C)
2.If the I of the pulley is not zero then the answer is A
@PhysInHistory Answering yes,is like agreeing for a creator.But then,we must agree that the same creator has build large amount of similar simulations. And maby there are many creators living in ther own simulations. Too much complexicity. Don't you think?
@harpap36@dstefanos Για τον ίδιο μιλάμε. Δεν μου μοιάζουν για φύτρες. Τον είχα δει και σε άλλη φωτογραφία πριν ένα μήνα και ήταν στο ίδιο σημείο. Για τατουάζ μου φαίνεται.
