Combined Stress - Axial and Bending (Superposition)

[@nahommerk9493]

You're a great tutor! Your explanation is so clear and fruitful. You remind me of Sal Khan from Khan Academy. :)

[@thetennerz6093]

just love your explanation thanks for the help👍👍

[@Palmec_2112]

Thank you for your presentation.

Is there a reason why we excluded the shear stress from this question completely? We solved for Ry but didn't get to use it regarding the sum of forces. ( normal stress + bending stress, excluded shearing stress)

Great work Sir

[@enjeanr]

you sound like morty from rick and morty :) your explanation is so clear also

The moment caused by the force of 30 N is negative.

[@MarkMattsonPE]

Yes, the moment is negative internally as it causes tension on the top and compression on the bottom. Since it's drawn that way in the FBD, the sign when solved is +, showing the assumed direction (negative moment) is correct. This is definitely a confusing topic. It's the difference between the FBD sign convention versus internal moment sign convention. Does that help?
