Determine the force in members KJ, KC, and BC of the Howe truss, and state if the members are in tension or compression.

Step-by-Step Solution

Solution 1

Free body diagram of whole truss:

We know that

From triangle JGD

From similar triangles

Now taking moment about G

Resolving the forces along x-direction

At Section:

Taking moment about K

Resolving the forces along x-direction

Similarly, resolving the forces along y-direction

Therefore forces in the members
