transverse shear stress and flexural stress without knowing the
location of the maximum shear and moment? Explain your answer.

Expert Solution
Yes, it is possible to obtain maximum value of transverse Shear
stress without knowing the location of maximum transverse Shear
force.
If you are giving the value of maximum transverse Shear force,
you can calculate maximum transverse Shear stress.( formula is
written on the paper).
But, to obtain maximum transverse Shear force you
should know the location of maximum transverse Shear
forforce.
Yes, it is possible to obtain maximum value of flexural stress
without knowing the location of maximum bending moment.
If you are giving the value of maximum bending moment, you can
calculate the maximum flexural stress.( formula is written on the
paper)
But to obtain maximum bending moment you should know
the location of maximum bending moment.
Explain why the concept of shear ductility is revised through a
maximum capacity to shear and why this is a function only of the
strength of the concrete.
(c) Draw a schematic graph of resolved shear stress versus shear
strain for a single crystal of a pure metal. Clearly label the
point of the critical resolved shear stress and the three
subsequent stages of dislocation behaviour. Describe these three
stages.
(d) Explain why the critical resolved shear stress is much lower
than the theoretical strength, based on the force required to break
atomic bonds within the structure.
A 2 by 4 wood beam (E = 2000 ksi) with an allowable flexural
stress of 1200 psi is subjected to bending around it's strong axis.
Determine the % increase in flexural moment capacity if the beam is
reinforced by 2 0.25" steel (E = 30000 ksi) plates with an
allowable flexural stress of 24000 psi at the top and the bottom of
the beam respectively.
