A 115-mm-long beam supports a load of P = 26 N at midspan. The cross section is rectangular with width b = 30 mm and height h = 45 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.

A continuous beam’s flexural reinforcement must extend at least _____ from the point where it is no longer needed to resist tension. Assume f’c = 4,000 psi, fyt = 40,000 psi, b = 13 in., d = 17 in., and that there are four No. 7 longitudinal tension bars and No. 3 stirrups at 7 in. o.c. The stirrup hooks are 135°.
