Problem 4: For the beam shown, use Matlab to calculate the deection at the midspan using four beam elements, making the shear area zero and then making the shear area equal 5/6 times the crosssectional area (b times h}. Then make the beam have decreasing spans of 200 mm, 100 mm, and 50 mm with zero shear area and then Sf times the crosssectional area. Compare the answers. Based on your program answers, can you conclude whether your program includes the effects of transverse shear deformation? 150.9(1) 5 100 mm -| _...| la b: 25 mm .ll'l'l mm
