Find support reactions at A and B and then calculate the axial force N, shear force V, and bending moment M at mid-span of AB. Let L 5 4 m, q0 5 160 N/m, P 5 200 N, and M0 5 ? 380 N m.

Explanation:

It is given that .

Thus taking equilibrium in x-direction (horizontal)

∑ ⇒

Taking Equilibrium moments for point A.

Giving ∑

Thus

So it can be written as

Now taking Equilibrium in y-direction (Vertical).

∑

thus it becomes as

it can be written as

Now, As for equilibrium in x=direction

∑ ⇒

And for equilibrium in y- direction

∑

it can be written as

Now taking equilibrium of moments about A,

∑

it can be written as
