Physics: Torque and static equilibrium

AI Thread Summary
The discussion centers on a physics problem involving torque and static equilibrium, where the original poster scanned their working attempt. They acknowledge an error in using the mass of 21kg instead of the correct 21.5kg, leading to incorrect calculations. A key question is raised about whether the tension in the cable has a y-direction component. The participants are encouraged to analyze the diagram closely for clarity on this aspect. Overall, the focus is on correcting the calculations and understanding the forces involved in the scenario.

I don't like writing formulas on the computer, so i just scanned my attempt.

In my working out, i incorrectly use the mass of 21kg for the light, it's actually 21.5kg...but either way my working out is still incorrect.

Thanks in advance, Frantelle.

Look closely at the diagram, does the tension in the cable actually have a component in the y-direction?
 
Thread 'Minimum mass of a block'
Here we know that if block B is going to move up or just be at the verge of moving up will act downwards and maximum static friction will act downwards Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
