Question

5. To what degree is the following beam with two fixed ends statically indeterminant? a. 1st Degree F b. 2nd Degree c. 3rd Degree d. Beam is structurally determinant F *Т H 1 a. 6. The centroid can be defined as The center of gravity for a body of various materials b. The geometric center of an object The point where a moment of inertia is always taken about d. All the above C.

Answer 1

5. Since, given beam has general loading system.

So, static indeterminacy = no. of unknown reactions - equilibrium equations

So, D_se = (3+3)-3 = 3

Option, (c) 3rd degree is correct.

6. The centeroid is center of gravity of body of various materials , geometric center of the body , point where a moment of inertia is taken about.

So, option (d) all of above is correct.
