Strength Of Materials Practical Task 3 33 4. A cantilever with cross-section as in Figure 4 is subjected to a concentrated load of 20 kN at the free end. specify: a) the maximum deflection of the beam b) the maximum slope/gradient. c) if additional uniformly distributed load of 150 N/cm applied on the beam, calculate the maximum deflection of the beam. Given E = 200 GPa 5. A cantilever with 3 m in length carry a uniformly distributed load of 5 kN/m along the beam. Determine the maximum deflection of the beam if the beam cross section as shown in Figure 5 and the Young's Modulus is 205 GN/m 2 . 6. a) A cantilever beam, 6m in length is subjected to a uniformly distributed load w N/m on the entire length of the beam as in Figure 6 below. Determine the value of b if the maximum deflection does not exceed 15mm and the maximum allowable bending stress is 100 kN/m 2 . b) If the same beam in question (a) above is replaced to a simply supported, determine the value of a uniformly distributed load, w. Take the value of E = 11 GN/m 2 . 12 m 2 cm 20 kN Figure 4 8cm 6m w N/m b 2b Figure 6 all dimension in ‘mm’ 120 140 100 20 20 Figure 5
