These are the solutions to the problems, can you please show me the steps to reach this solution? Thank you so much! 7. Write the load function w(x) and the boundary conditions for the following beam or beam-column problems. Variable y is deflection and the range of the independent variable x is [0,L]. (b) End B is roller support with an eccentric loading P. (c) A beam-column is pin supported at both ends. The end moments are MA and MB, respectively. (d) A cantilevered beam under linearly distributed loads as shown. The maximum load intensity is W0 (in a unit of Force/Dimension, such as kN/m ) (e) Transverse loading is a uniformly distributed load q. The right end is fixed. The left end is allowed to move freely in vertical direction but rotation is prohibited. The origin of the coordinate is taken at the undeformed position of its left end (i.e., the coordinate origin will not move down with the left end). Review Questions: Could you explain what the notations represent in each figure? How the sign conventions impact your formulation? 7 (b) load function: w(x)=0 due to zero transverse loads between the two ends. Boundary conditions: 7(c) load function: w(x)=0 due to zero transverse loads between the two ends. y(x=0)=0 y(0)=EIMA, where MA is negative according to sign convention y(x=L)=0 y(L)=EIMB, where MB is positive according to sign convention 7(d) load function w(x)=W0(1Lx) Boundary conditions are: y(0)=0 for zero moment, y(0)=0 for zero shear, y(L)=0,y(L)=0 7(e) load function w(x)=q Boundary conditions are: y(0)=0 for zero slop, y(0)=0 for zero shear as V=EIy,y(L)=0, y(L)=0
