### Mechanism and static determinacy

The answer for b) should have a redundancy of second degree - j = 6, r = 6, b = 8, i = (b+r) - 2j = (8+6)-2*6 = 2. For c), redundancy of third degree - j = 5, r = 6, b = 7, i = (7+6) - 2*5 = 3. For ...

### Symmetry to determine the support reactions of a statically indeterminate frame

The members and loads of the frame are symmetric about joint "B", but the supports are not, which is the source that causes non-conforming deflections when loaded. The sketches below depict ...

### What is the cause of this cracking pattern in a simply supported beam?

Below is my inspection. Note the cracks between the support points - from diagonal near support and gradually turns vertical towards the midspan. Street View: The cracks in the circle forms the ...

### Is it valid to solve for the young's modulus required for a given critical load with Euler Columns?

Yes you can use the formula to solve for an acceptable modulus of elasticity (E) that prevents buckling. Like any mathematical formula that relates 4 variables, you can calculate any variable based on ...
