Question #$1$

The elevation view of a two$-$span post$-$tensioned concrete girder is shown in the figure below. The tendon profile is symmetrical about the pier centerline. Assume: $1)k=0\mathrm{.}0008$ per ft and $=0\mathrm{.}4$; and $2)$ the left end in the figure $($i$.$e$.,$ End $"$A$")$ is a live end and the right end is a dead end. The stress in the prestressing tendon at jacking is $189$ ksi $.$ Determine friction loss at location $"$E$"$ over the pier.
