Solving Shear Force and Bending Moment at Reaction Point R
Well, PhanthomJay, thank you again for all your timely help - far more than I expected! I've learned a little more. Most appreciated. Kind regards, Fred- fredmahy29

Solving Shear Force and Bending Moment at Reaction Point R
OK thanks again. So the (horizontal beam) BMD starts off -ve at the cantilever fixing point and continues unchanged to the RHS of the beam; the fixing moment being anticlockwise which balances the clockwise moment at the RHS of beam. This time perhaps?- fredmahy29

Solving Shear Force and Bending Moment at Reaction Point R
Yes, I understand 1st and 2nd para results (although I thought since beam would hog with weight the moment at R would be negative by convention). And I'm afraid I can't find any shear force along the beam! So obviously I still haven't grasped the concept! Thanks for bearing with me on this!- fredmahy29

Solving Shear Force and Bending Moment at Reaction Point R
OK thanks. So now the way I see it ... Horz reaction at Rh = -F Vert reaction at R can only be due to gravity … something like Rv = -(beam weight*beam length + vertical [baluster] weight) = shear at R Any closer? Thanks again for all your help :)- fredmahy29

Solving Shear Force and Bending Moment at Reaction Point R
Thanks PhantomJay But this is where I'm stuck. To me, reaction R = 0 (surely it couldn't be that R = F?), which is counter-intuitive. Another clue perhaps?- fredmahy29

Solving Shear Force and Bending Moment at Reaction Point R
Hello Please see attached - trying to figure shear force and bending moment at reaction point R, with a horizontal force applied at top of Z. This is a veranda deck with balustrade. If F was vertical, then straightforward with SF = F and M = FX. But when F is horizontal as shown, I'm having...- fredmahy29
