Consider a beam supported with a roller on one end and fixed on the other end (see the Figure (a) below). The beam is subjected to a linearly increasing distributed load (w_(0)). Figure (b) The function that represents the elastic curve (dotted lines) in Figure (b) is as follows: y=(w_(0))/(120EIL)(-x^(5)+2L^(2)x^(3)-L^(4)x) where: L=450cm,E=50000000(N)/(c)m^(2),I=30000cm^(4) and w_(0)=17500(N)/(c)m. Apply the bisection method to find the point of maximum deflection, which occurs where d(y)/(d)x=0. Once you have identified this value of x, substitute it back into the original equation to calculate the maximum deflection. Hint: Think carefully about the number of iterations you might need to get to the answer. 2.1 Provide the steps to show that the Q-h relationship for the channel can be represented by the following equation: Q=(((h^(2)+hcot(\theta ))^((5)/(3)))/(0.014cot(\theta )))((sin(\theta ))/(2h+cos(\theta )))^((2)/(3))(0.009)^(0.5) Where \theta is the angle of the sides of the channel and hh \theta = 45\deg and you know that h falls between 0.3 and 0.6 m . Hint: f(h)=(((h^(2)+hcot(\theta ))^((5)/(3)))/(0.014cot(\theta )))((sin(\theta ))/(2h+cos(\theta )))^((2)/(3))(0.009)^(0.5)-1.8 The diagram below represents a trapezoidal concrete channel designed for stormwater drainage. The bed slope (S) is 0.9% and Manning's coefficient (n) is 0.014 . The estimated discharge (Q) is 1.8(m^(3))/(sec). The discharge or channel dimensions can be determined using Manning's formula: Q=(A)/(n)R^((2)/(3))S^((1)/(2)) Where: Q=discharge((m^(3))/(s)) A= flow area (m^(2)) R= hydraulic radius (m)=(( Area )/( wetted perimeter )) S= slope ((m)/(m)). 1.5 Provide the R commands (or any programming tool of your choice) and a screenshot to show the plot, including a title and labels on the horizontal and vertical axes, for the following equation: M=12.5x-0.75x^(3) x is to be defined from 0 to 5 at an interval of 0.05 Title: Bending Moment Diagram Horizontal axis label: Distance along the beam (m) Vertical axis label: Bending Moment (kNm)
