# reaction of structure

all is this sturcture stable ? or structural determinate ?

Let the top support as A , bottom support as B ,

By taking moment about A, i managed to get 10(4*4)/2 -HA(2) = 0 , HA = 40kN,

HA = HB = 40kN ,

By taking moment about C , i managed to get -10(4*4/2) + 4(VB + VA) -40(2) = 0

VA + VB = 40kN , however , i still not able to get the exact value of VA and VB, where did i miss out ?

• is this structure in a single plane? i.e. xz? It's difficult to tell from the drawing. Also is there an angle on the beam with the distributed load? Is the load uniform? Nov 28 '20 at 20:25

The beam ac is a simply supported beam with uniformly distributed load of 40N so the reactions are

$$V_B=V_C=40/2\rightarrow V_B=20N$$

$$\Sigma V=40,\ V_A=20N$$
