in getting the normal stress in the Y axis (for point H) why did we not include the compressive force 2500 ? i think it still experiences normal compressive force but there is no stress due to bending moment.
@@engradnanrasheedmechanicalyou added the normal compresive stress (2500 lb) in the stress at x axis, so why would not we add it in the stress at y axis?
@@engradnanrasheedmechanical There are two moments on each axis, also torsion.. It's mind blowing when trying to figure out what are the moments acting on each axis
@HashemAljifri515 yes first 2 times it will be difficult but when you try yourself i am hopeful that you will get it. Try to think and try to solve it by your self after pausing every step try to do it on paper.
H lies on the outer surface and away from neutral axis and area about H is 0 so Q is zero. While K lies on neutral axis and there is area above K which is not equal to 0 . That's why its Q is not equal to zero.

In y direction there is no normal force . You can check that again. Thank you
there is, due to force in the z direction (which acts perpendicular to the cross section)
@kc9487 which will be normal stress in z direction

@kc9487 normal compressive stress is not in x direction its along z direction.
Can you explain why the clockwise torque around the z-axis isn't negative? Is the problem making the clockwise direction positive?
Torque about z axis is negative.
What a chapter man!! Very confusing
why is it so confusing for you?

Why hocam k is not a neutral axis I think torsion will be zero?
NO K IS ON ITS ON OUTER BOURDRY OF CIRCULAR PIPE. TORSION IS NOT ZERO....
Why is Q zero at H but not K. They both lie on the edge of the circle
