1. The problem statement, all variables and given/known data It is given in the photo 2. Relevant equations They are all given in the photo 3. The attempt at a solutionI solved exactly the same as in the solution manual, except for the FBD of the slider B, when they write the 2nd Law, they do not input the weight there, only the Tension force by the rod.Why did they do that, that was the part I did not understand. Note: For the B block they use the x-direction as vertical.
