3. Fig 2a shows a uniform beam subject to a linearly increasing distributed load As depicted in Fig 2b, deflection (m) can be computed with 90 (-x* + 2 Lx? 2^x) where E-the modules of elasticity and 1-the moment of inertian (m) y 120 E IL Fig. 2 (L) ne21 The slope, moment, shear force and loading can be computed by the following equations respectively dy 90 Slope: 0(x) (-5x* + 6 Lr? - 2) 120 BIL Moment: M(x) = ET dx 90 (-20% + 121 x) 120 L Shear V(x) = ET dx 90 120 (-60x? +122) dx L b Loading 9x) = -1 90 40* 1202 (-120x) = Write a function called "beam" that determines deflection, moment, thear and loading corresponding to each x value (25) Write a M file that writes the results of the beam finction" to beam_out, txt and employ the subplot function to display all the plots of deflection, slope, moment, thith and loading versus the distance along beam vertically on the same page (25) Use the following parameters for your computation L-om, E-5 104 kN/m, 1-3 10+m1.go-250 N/m and Ax-0.Im
