Question

The reinforcement shown is made up of twelve bars of equal length L, is linked to the ground by the flat joints A, H and J. If the reinforcement is subjected to the indicated load system; determine:

a) The reactions in the joints.
b) The force on the BG and GD bars.

Answer 1

To determine the reactions in the joints, use the principle of moments. To find the force on the BG and GD bars, analyze the forces acting on each bar and use Newton's second law.

Step-by-step explanation:

To determine the reactions in the joints, we can use the principle of moments. By taking moments about each joint, we can set up equations to find the reactions at joints A, H, and J. The sum of the moments must be zero for equilibrium.

To find the force on the BG and GD bars, we can analyze the forces acting on each bar. By considering the equilibrium of each bar, we can calculate the forces using Newton's second law, F=ma.
