For the rigid frame shown determine a the nodal displacement

For the rigid frame shown, determine: a) the nodal displacement components and rotations, b) the support reactions, and c) the forces in each element. Let E_1 = E_2 = E_3 = 200 GPa, A_1 = A_3 = 2 time 10^-3 m^2. A_2 = 1 times 10^-3, and l_1 = I_2 = I_3 = 5 times 10^-5 m^4, L_1 = L_3 = 3 m

Solution

from the above given data the nodal displacement can be calculated as follows

nodal displacement arae are as follows = 25 m , 39 m

reactions are as follows = 235 n , 69 n
