Question

Two posts are stabilized by wires attached to a wall. Each wire exerts a force on a post at points B and C as shown. What is the purpose of the wires?

1) To prevent the posts from falling
2) To provide additional support to the posts
3) To increase the height of the posts
4) To decorate the wall

Answer 1

The wires are used to prevent the posts from falling and provide additional support to the posts.

Step-by-step explanation:

The purpose of the wires is to prevent the posts from falling and to provide additional support to the posts. The wires exert a force on the posts at points B and C, which helps to counteract the downward force of gravity and keep the posts stable. Without the wires, the posts would be more likely to topple over.
