Question

NOTE:

Problem #4 (correction): Answer for the angle is = 21.2 (degrees)

PLEASE ANSWER BOTH QUESTIONS FULLY. THANKS.

3. Using the generalized moment-curvature formulas, prove deflection can be expressed as follows for a cantilever beam that is subject to pure bending. Calculate the stress at A and the tip deflection for a cantilevered beam with the cross-section shown in Figure 2. Assume a positive moment about the y-axis (My) is applied at the free end of the beam. Let h = 6 in, b = 4 in, a = 2 in, t = 0.5 in., M, = 15 kip-in, and E-30x 103 ksi. The length of the beam is 6 feet. Answer: σ.:-5.9 ksi, δ = 0.318 in directed 27.4. cov from z-axis t (all Figure 1 Figure 2
