Problem $1$

Numerical Problem $(15$ points$)$:

$(5$ points$)$ Draw an 'exploded' view showing multiple FBDs of the system using the standard positive conven$-$

tion$/$notation for the internal normal forces, as done in class. As for the support reaction, you can assume those

to be vertically up and to the right as done in the class $($we will talk more about convention for support reactions

in a few weeks$).$ Your FBDs should be made of straight lines using a ruler.

$(10$ points$)$ Calculate the internal normal forces in CB and CA members assuming that angle $$ is $65.$
