The correct statement about the relation between the shear stress (force) at the surface for laminar and turbulent flow over a flat plate is. a. The laminar shear stress is greater because the fluid viscosity is not important in turbulent flow. b.

How many sets of equations (V and M equations) would you need to describe shear and moment as functions of x for this beam? In other words, how my segments of the beam need to be analysed separately?
