The section shown below is for a semi$-$circular nosed pier used to support a bridge crossing over a river. The pier height is $25ft.$ and is fixed at the base and pinned at the top. During winter time it has been observed that the river surface turns into ice floes covered with snow. The table provided below presents the results of a survey conducted to determine the Average Daily Air Temperature at the bridge site. Use the information provided below to draw bending moment and shear force diagrams of the pier $($about both pier axes$)$ due to water flow and dynamic ice forces.

Data:

Design water velocity $=4\mathrm{.}0f\frac{t}{s}$

Water flow angle with respect to the longitudinal bridge axis $=70$

Assume that the ice forces are computed at the ice melting point when the ice is somewhat disintegrated.

Friction angle of ice $=25$

River depth $=10ft.$
