A cantilever beam of length L has the cross section shown in Figure P7.34 and is subjected to moment M at its free end. Determine the deflection of the free end in terms of E, L,Μ, ψ, and h. Consider only the case for which 0 ≤ ψ ≤ 90°.

A beam has a square cross section (Figure P7.34).

a. Determine an expression for σmax in terms of M, h, and ψ.

---

b. Compare values of σmax for ψ = 0, 15, and 45°.
