Beer & Johnston — Shearing Stresses in Beams: Problem 6.25

6.25 through 6.28 A beam having the cross section shown is subjected to a vertical shear \(V\). Determine (a) the horizontal line along which the shearing stress is maximum, (b) the constant \(k\) in the following expression for the maximum shearing stress \[\tau_{max} = k \frac{V}{A}\] where \(A\) is the cross-sectional area of the beam. For 6.25: The cross section is a solid circle with radius \(c\).
