Hello everyone, i tried to solve this excercise of the kinematic and im not sure if my calculations are correct. Please give me feedback and help for c). The text is in german, it says: A massless and inextensible rope attached to the ceiling is guided around a massless pulley 3 and then...

Soryy guys english is not my first language. This was really helpful and i appreciate that.

Hello Community, i need help in defining the connection between x3 and x1 (kinematic constraints). My Professor can´t explain it well, im confused. Is there a scheme on how to determine the kinematic constrains? Task: A homogeneous cylindrical pulley (mass m1, radius r1) has a rope S1, which...

I tried to construct a instantaneous center of rotation and transmit the angles. https://files.engineering.com/getfile.aspx?folder=0e902bce-d8b3-4f69-a164-4969db50e916&file=IMG_2145.jpeg

I don´t get how to determine the vector r(AB). I know that i have to transmit the given angels. Please help me guys. The Solution is r(AB) = (-√3*a,a,0) Task: A rod 1 becomes vertical at its end A and at its End B guided horizontally. In the middle M is a second one Rod 2 is rotatably...

Topic: Application work -energy equation. In the solution, a reference point (a zero level) is chosen. Unfortunately, I absolutely did not understand how to determine the reference point. I would choose from point A to point B. How do I determine the reference point? The solution also says that...
