If i take a look at Beam AD as free supported at A and D i get Maximum bending moment to 75 N*m by m.max = (1/8)*w*l but I guess its wrong because I didn't consider internal reactions at B and C - how did you find the momentum curves from A to D - could you tell me your approach ?
Hey, the dimensions are
AB = 0.6 m
BC = 0.2 m
CD = 0.2 m
AE = 0.45 m
Furthermore (for all members)
E = 200 GPa (steel)
I = 0.04 * 10^6 mm^4 (beam 30x30x3,2 mm)
A = 343.04 mm^2 (approximately)
And the beams are welded. It is for a project where we are construction a vehicle (so E and...
I need help for this structure. It is loaded as shown - point E and G is wheels added as free bearings. I need to know the bending in Beam AD and also EF.
I tried isolating beam AD and see it as an statically inderteminant beam to the second degree - but i am not sure this is the right...
