It says they are pin connected together. I agree the diagram is unclear though.

Wrong.

I'll fix up your LaTeX by replacing each occurrence of [ tex ] and [ \ tex ] with a double #. It is clearly not valid to conclude that...

In the diagram, F is applied to GE, so would not feature in any equation specific to ACDG. Please post your equations.

You are missing a force at D on ADC. Likewise at E on CEB. In your moment sums, you need to be clear on the system you are...

Several things. Velocity is a vector. What does it mean to say a velocity is at its maximum? Ok, we can say that its magnitude is at...

That's a different matter; the discussion was confusion between mass as an object and mass as a property. English is replete with puns...

Quite, because those velocities represent available choices and it is reasonable to rank choices based on the outcomes. What makes the...

But elementary physics texts regularly use shorthand terms like "point mass" (not "point object with mass") and "point charge" (not...

That would have been clearer, yes. But consider.. 1. "Cars of velocities v1 > v2 > v3 are driven from A to B. Rank the cars in order...

The wording is awkward but not actually wrong. It means rank the fluids according to the buoyant forces they are exerting, but since...

I have always assumed that Archimedes figured this out by imagining replacing the submerged portion with an equal volume of water...

What did Archimedes realise about the quantity of fluid displaced by a floating object?

To my eye, those two curves look different. The second is close to being a quadrant of a circle but the first exhibits changing...

That analogy works, but it is not clear how you used it in this question. I assume you reversed it, so taking the given E/x graph as...
