Problem $1$: $($a$)$ If a column subject to axial compression load caused by dead load $Pd=1000$ kips and axial compression load caused by live load $PL=120$kips. There is no axial compression caused by other load. What is the design compression load on the column $Pu=?$

$($b$)$ In a truss member, axial tension load caused by dead load $Td=200$kips, axial tension load due to live load $TL=150$kips, and axial tension load caused by wind load $Tw=300$kips. There is no axial tension load caused by other load. What is the design shear at the section Tu$=?$

Problem $2$: Determine the smallest net cross$-$sectional area of the following section. All holes are standard holes with a diameter of $1^{\text{'}\text{'}}.$
