Part I. Shorter problems focused on the fundamentals

The frame shown is pinned at A and at E and is loaded with a force, $F=41lb,$ and moment $M=209ft-lb$

$(CW),$ and the dimension, $a=6\mathrm{.}1ft,$ and $b=4\mathrm{.}2ft.$

a$.$ Draw a free body diagram of member ABC $,$ how

many unknowns are on the FBD$?$

b$.$ Draw a FBD of member CDE, how many

unknowns are on the FBD$?$

c$.$ What is the x $-$component of the connection force at C on member CDE?

d$.$ What is the y$-$component of the connection force at C on member ABC $?$
