Consider the loaded cantilevered beam as shown in Figure Q3. The cross section of the beam is also shown, where b= 5 cm and h = 10 cm. The applied force, P= 1.2 kN.

(a) Find the absolute maximum value of the shear stress, |????????????????| anywhere on the beam

(b) Find the absolute maximum value of the bending stress, |????????????????| anywhere on the beam, in terms of the beam length L (Hint: You will need to find the maximum bending moment anywhere on the beam first).

(c) Determine the length of the beam, L so that the maximum bending stress is 100 times that of the maximum shear stress, i.e., |????????????????| = 100|????????????????|
