Problem $2$: $($statics course, sophomore year$)$

Five members of a truss connect at a joint. An applied

load of $120kN$ acts on the joint. The forces for the

members acting in tension are shown. Determine the

resultant force for the five forces shown.

Step $1$: For each force, calculate the $x$ and $y$

components of the force.

Step $2$: Sum the $x$ and $y$ components

Determine the magnitude and direction of the

resultant force.

Step $3$: Determine the resultant magnitude and

direction. Use the sign convention shown: note the

angle is measured from the $x-$axis, positive counter$-$

clockwise.
