Q2: For the beam shown in figur , determine the value of I that will limit the maximum deflection to 20 mm. Use E=10*10° N/m². 600 N/m- 1 m 2 m

Problem 2 (30 points): The formula for the deflection of the beam shown is: Wo y(x) = (-x5 + 5Lx-10L?x3 + 10L³x²) 120LEI Wo 15 x 107 N L = 2m %3D max m E = 7 × 1011 N m2 I = 6 x 10-4m Use the Newton-Raphson Method to determine the x location along the beam where the deflection is y(x) = 0.14 m. Use a starting guess of xo 1.2 m. Be sure to show your %3D calculation for the derivative of the function and your calculations you use to fill out the table. You only need to perform two iterations of the method, which means you should fill out the table below. Notice that y is defined as positive in the downward direction, which means that both the function and the target deflection are positive values in the coordinate system. y(xn) y'(xn) Xn+1 Step Xn 2.

Given the beam and the loading shown below, if L = 5 m, W1 = 4.5 N/m and w2 = 22.3 N/m. Calculate the vertical reactions at the supports. W2 w(x)=w, +ax³ L A B X Reactions: Ay = 单位 (tolerance 0.5 N) By = |数字 单位 (tolerance 0.5 N)
