Not that big of a deal but M_A should be in kN•m not N•m. Other than that, great video, thank you so much
You are welcome! Thank you for pointing it out. I pin your comment so others could see it immediately upon watching the video.
Why the last one you said Fb is positive is the actual value?
how did you find by=7.5 kn I didn't follow
After finding Cy and Dy, we write summation of forces in y direction to find By.
Because Ax is the only external force in the x direction, can't we just assume that it is 0? The math does follow.
Correct, you do not need to include Ax, however, I usually instruct my students to write all the reaction forces a support can have and show it with math if a reaction is zero.
