Dependent motion - cable (rope) velocity

[leonel]

Hi, fellows !
In an arrangement of 2 slinding blocks connected by a cable (rope). I can state the blocks position and their velocity as a consequence. On the other hand, i can't figure out the cable velocity...which concept should I apply for ?


VB=18in/s > (Info)
VA= 27 in/s > (found)

What about the cables D and E velocity ?
Cable C has the same veloc of block B.

Thanks, Leonel

I would say the cable velocity is equal to the velocity of B.

Hello Leonel,

I would suggest using the concept of relative motion to determine the velocity of the cable. Since the blocks are connected by the cable, their velocities will have an impact on the cable's velocity. You can use the equations for relative motion to calculate the cable's velocity based on the velocities of the blocks.

Additionally, the velocity of the cable can also be affected by factors such as tension, friction, and the weight of the blocks. It would be important to take these factors into consideration when determining the cable's velocity.

As for cables D and E, their velocities can also be determined using the same concept of relative motion. However, it would be necessary to know more information about the setup and the forces acting on these cables in order to accurately calculate their velocities.

I hope this helps. Good luck with your research!
