Members AD, DC and ABC are assumed to be solid rigid members; member ED is a cable. For this structure, determine the reaction at A, the tension on cable ED and the force in member DC.

Link for the structure:

In Figure 1 and using Method of Sections, find the force in CD, BC and AC if the load acting at Joint C is decreased to 2,500 N.

link of figure 1:

In Figure 1 and using Method of Joints, find the force in each of the members and indicate if the they are in tension or compression.
