Hey guys,
A picture of the question is attached, I am not seeking answers just an explanation of some theory.
Now I understand that
point A will be under compression due to the weight, tension due to the bending and shear due to torque produced by the wind
point b will be under compression due to weight, tension due to bending (but different tension to point A because of the different moment) and shear due to torque produced by the wind
point C will be under compression due to weight and compression due to bending and shear due to torque produced by the wind
Now when applying the bending stress equation (MY/I) wouldn't either point B and C together or point A on its own lie on the neutral axis? And hence the bending stress would be zero Or would Y (distance from the neutral axis) always be 50mm?
