Problem $2$

A beam with two moment releases is shown below $($Supports B and D are roller supports$).$

Complete the following tasks related to this structure:

Verify the structure is statically determinate

Use the Mueller$-$Breslau principle to develop the influence lines for the following quantities:

$$ Support reactions $R_{Dy}$ and $M_F$

Bending moment at Support D

Shear force to the right of Support D

Consider a gravitational uniform live load with magnitude of $1klf,$ use ILs to determine the

patterns and the magnitudes of the live load effects below

The maximum negative moment at Support D

The maximum absolute value of shear force to the right of Support $D$ Answer all parts to the question in clear writing
