Solution

ANS:   TRUE

In2d multy member frame system it is TRUE that sometimes necessary to brake the frame into individual members to solve the internal forces

While analysing 2D frames having Degree of Static indeterminicy is less than Degree of Kinamatic Indeterminacy(Ds<Dk). We will go for a)Slope Deflection Method ,b) Moment Distribution method Or c)Kanis Method for internal forses like shear force, bending moment.

In all the above three methods, unknowens are displacements. Ones we got these unknown displacements it is easy to get internal forces.

To find these displacements (slopes and deflections), Equlibrium Equatins are are to written.

Equillibrium equations are

1) Joint equlibrium equations 2) shear equations,

To form these above equations we will brake the frame into individual members and get the equations followed by internal forces.
