NOTE: BELOW I UPLOADED ALSO A SIMILER EXAMPLE AND SOLUTION FOR TO GET HELP JUST GO THROUGH THAT EXAMPLE AND SOLVE UPPER QUESTION ACCORDING TO THAT THANKS...

1. Given Figure 1.0 and Figure 1.1 below and that bending is about the XX axis, complete the following tasks a). Construct the shear force diagram b). Using the shear force diagram construct the bending moment diagram using areas c). Construct the axial force diagram d). Determine the centroid of the section e). Determine the second moment of area

A proposed design for a hydroelectric project is based on a discharge of 0.25 m 3 /s through the penstock and turbine (Fig. P12.50). The friction factor can be assumed constant, f = 0.015, and the minor losses are negligible. (a) Determine the power in kilowatts that can be expected from the facility, assuming that the turbine efficiency is 0.85.
