Question
For the truss structure and the loading case shown, the pulley at D can be treated as frictionless.
a. Calculate the resultant force magnitude
and direction that the pulley exerts on
the truss at joint D.
b. Calculate the reaction forces on the
truss structure at supports A and C.
Show the components of these reaction
forces on a free-body diagram of the
structure.
c. Calculate the internal forces (magnitude
and T or C) in all members of the truss
Make sure to show labeled FBDs that
support and explain your calculations
