To find the reactions at point A in a structural system, it is necessary to calculate Ax. The equation Ax - 400cos30 = 0 is correct for determining Ax. Additionally, the calculation for x, using the equation 300(20) = 100x + (400sin30)x, is validated by other participants. The discussion emphasizes the importance of these calculations for accurate results. Overall, the approach to finding reactions and the value of x is confirmed as correct.

I am to find the reactions at A. Am I doing this right? Do I also need to find Ax? If I do, would it just be Ax - 400cos30 = 0?

Yes, but I couldn't find your calculation for determining x =20 feet
Do I also need to find Ax?
Yes!
If I do, would it just be Ax - 400cos30 = 0?
and Yes again!

My bad. I used this following equation to find x.

300(20) = 100x + (400sin30)x

Is that the correct way of finding x?

Yes, indeed.:approve:
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
