Given is a shear-force V = 4000 N acting vertically downward
on the beam cross-section as shown. Determine :
- the central moment of inertia
- the shear-stress at top and bottom of beam, y=±h/2
- make a rough sketch of Q(y)/b(y) as function of y. What happens at y=± (h/2-t) ?
- the shear stress in the neutral axis ( y=0 )
- Is the value determine under 4 the maximum ?
h = 6 cm
a = 4 cm t = 1 cm
