[Terjawab] What's one supporting point for using hydroelectricity for energy?

[Terjawab] A simply supported beam is subjected to uniformly distributed loads: a service dead load [tex]w_D=5 kips / ft[/tex] and a service live load [tex]w_L=7 kips / ft[/tex]. Use the load combination [tex]w_u=1.2 w_D+ 1.6 w_L[/tex]. Note that the shear force is expressed as [tex]V_u=w_u(\frac{L}{2}-x)[/tex] where [tex]x[/tex] is the distance from a support. (65pts total) The beam also has the following properties. [tex] \begin{array}{c} f_c=4 ksi, \quad f_y=f_{yt}=60 ksi, \quad b=18 in \ h=26 in, \quad d=24.5 in \end{array} [/tex] No. 4 bars, U-stirrups used, Normal weight concrete (1) Calculate the required spacing of stirrups.
