Please tell me the author's name or journal. Or just provide the DOI, which will contain all the required contact information. --- End quote --- Can you tell us about the results of your conversations with the authors? |

How can it be stopped with a bare hand (in the video)? --- End quote --- 1. where did you see 1 rpm? 2. how did you calculate 1600 Nm without taking into account the pulley diameter? 3. in this video the operating mode is by no means optimal. The table shows the data in optimal mode. 4. watch this video. it looks like no one risks sticking their fingers into the pulleys |

Please explain. --- End quote --- In the same place where you saw 1 rpm. So where did you see it? How can you calculate the force applied to a pulley without taking into account its diameter? |
