Mechanical diagram of a bracket frame with a pulley at D carrying a cord loaded by a 300 N downward force; dimensions 180 mm and 120 mm horizontally and 150 mm vertically; pins labeled B, A, C and E, with member BC attached to a wall.

Dont really need the answer, but I want to know if point C has Cx and Cy or just Cy. I am confused there.

Pinned connections generally take two force components, since they can support a force applied in any direction.

As a suggestion, find the equivalent forces to substitute on the frame for the weight suspended by the wire running over the sheave at pin D.
