Question
12) The shearine stress wi the outer surface of a beam i 13) At the principal stresses, the shearinu ness is When analyzing a structural with multiple loads that each produce a normal stress along ve same axis, the resultant normal stress is deermined by multiplying them together 15) The deflection at any beam support is 10) The product El is known as the 17) When compared to a pinned-pinned column, the critical load of a fixed-fixed column is: a) greater. c) the same. d) indeterminate. 18) T or F As the product El increases, the critical load of a column increases. 19) The unit for moment of inertia is: a) length b) length squared c) length to the 4th power 20) when performing a stress analysis of a s structure, the equations must be satisfied.
Explanation / Answer
11) F
Nomal stress due to bending is zero at Neutral axis.
12) Maximum
Shear stress is maximum at outer surface
13) Zero.
At principal stresses ther is no shearig stresses
