Im not sure if im wrong or im right... Compresive is not posive and tesile stress is negative??? If the top part is compressive and we apply the axial/direct force on the positive y axis, our axia/Compresive stress wont be positive??
for this chapter, it doesn't matter if you assume compressive as positive or negative, as long as at the end you will be able to tell if your resulted stress will be compressive or tensile. Henry Wickens assume compressive at positive. however, Du Toit use Tensile as positive.
Your channel is very helpful sir. Thank you and keep up the good work.
Thank you, I will
Mr Mahlaula you are the best, keep it up 😊😊
thanks for those words
Can you please do more videos on basics of sectional drawing and so how to draw an arc
Please do more of Moment of inertia.
