dx Q5 B) Find y" for the function y = x + Vx at p(1,3)

Calculate the vertical deflection of point B and the horizontal movement at D shown in the figure. Consider that all the elements of the truss are linearly elastic and have sectional areas of 1800mm2. Also consider an E of 200,000N/mm2. Add the calculation process of solving the problem step by step and complete the table accordingly.   L F FB   ∂FB / ∂PB FD ∂FD/∂PD AE     - 2√2/3 PB  -2/3 √2     EB             EF             AB             BC             CD             BF             FD             FC
