The vector sum of the lateral forces is zero. A zero force doesn't have to "come from somewhere".bobie said:where does it come from?
The lateral forces can be greater than the vertical one. Instead of an arc, consider a simple roof:bobie said:can the result of a force be grater than 100%?

What will be the ratio of horizontal to vertical forces when the slopes are less than 45°?
