Task 1: (15 Marks) A traffic signal pole is subjected to dead loads from signats and signage weights, as shown in photo below Thickness Thickness Diana Dia 0.75 Section - Section 2-2 Assume the typical weight of every sigral - 25 kg and the signage - 15 kg. Include the self-weight of the pole and the lateral arm (Both are steel pipes. Assume the wind leads as per QCS 2014 Assume the pole is fixed at the base. Make any assumptions required and state them clearly 1. Draw the Free body diagram for the traffic signal showing different applied loads. 2. Calculate the internal loads on the base of the pole. 3. Find the normal and shear stresses at point on the base of the pole. 4- Find the principal normal stresses and the maximum shear stress at point W on the base of the pole using stress-transformation equations 5. Find the principal normal stresses and the maximum shear stress at point W on the base of the pole using Mohr's circe method.
