Given is a shearforce V = 3000 N acting vertically downward
on the beam crosssection as shown. Determine :
 the central moment of inertia
 the shearstress at top and bottom of beam, y=±a/2
 make a rough sketch of Q(y)/b(y) as function of y. What happens at y=± t/2 ?
 the shear stress in the neutral surface ( y=0 )
 the location of the max shear stress ( it is NOT in the NS=neutral surface )
 the maximum shearstress

a = 6 cm t = 1 cm
