Q$1.$ The frame given is composed by $3$ rigid elements $($ ASBC,$CD,$DBE $)$ with negligible own weights. They are connected by pins at B$,$ C$,$ and D$.$

Frame is supported by a pin at A and roller at $C.$ BSEF is a continuous cable holding $10$ kN weight at F$.$ Pulleys at S and E are frictionless and weightless $($hint: radii of the pulleys are unknown and they are not required to solve the problem$).$

Determine the forces $($or the force components$)$ acting on the rigid member ASBC and show them on the free body diagram of ASBC.
