It's at sphere B which is the midpoint of CD. So i only need the vertical distance from the centre of mass when calculating the potential energy?

Then it would be like this. This was my first assumption but i got lost in the algebra and thought i was maybe wrong and it was supposed to be simpler

I do not understand if this just a problem treated like a pendulum with a simple sphere but just adding the other 2 sphere's masses. Is the potential energy supposed to have a different y for each sphere?

I move the system by a small angle θ . I am not sure if my calculations of kinetic and potential energy are correct.

For some reason i thought it's an eccentric loading problem but it's just σx=My*z/Iy due to P. Q axial force should not produce bending stresses only normal at point B of crossection.

If there is an axial load on G the centroid and i want to calculate the stresses at point B , I will calculate the moments at point B then use the stress formula. I am confused as to what y and z is in this case. I know that y and z are the coordinates of the point that i want to calculate the...

Anyone know of any book on mechanics of materials that covers finding the core of a section in eccentric loading. I am not sure what the term is in english but the direct translation is core of the cross section, it is the region in which if a load is applied, there will be only tensile or only...

I see, i will work the algebra and see if i can solve it, but i think there are too many unknowns.(##F_x##, ##F_y##, ##M_B##, ##L##, ##x## distance). And i only have 4 equations, one of each of the combined stress at each point. Thank you for your time and help

In order to find the bending moment at each point

I am not really sure, so if i cut the beam at points ##a## and ##b## ,both ##F_x## and ##F_y## will create a bending stress and ##F_y## also a normal stress? Would this be the way to solve it, cutting 2 times once at ##a## , ##b##, and once at ##c##,##d##

##F_y## okay thanks

F_y , not sure why it's not showing correctly in preview i copied your LaTeX code

I get it now

Fx * when perpendicular

you mean it should be clockwise to counteract the rotation that Fy creates?
