20 N

The tension at every point in the rope must be 20N, and it must exert 20N of upward vertical force on the top of the bag. If there's any point in the whole arrangement where the upward and downward forces are not exactly equal, then the mass at that point must be accelerating up or down.

20 N.

It's 20N IF the bag is just hanging there and not moving.If the bag is rising or falling, then the tension can be, but isn't necessarily,more or less than 20N.

The only way the bag of apples can have zero acceleration is that the sum of forces on it is zero. The 20-N downward gravitational force on it must be exactly canceled by some upward force of 20-N. That's the tension in the rope.

Assuming that all strands are vertical/ parallel to gravity and equally spaced (on a radius) around the centre of gravity then tension on each strand will be equivalent to weight x 9.81 divided by 7 equals tension in Newtons. If the strands are not normal and/or at varying distances from centre of gravity then it becomes a little more complicated. Summ of tension on strands must equal weight of bag. Tension on each strand is a ratio of it's distance from the COG of the furthest most strand. Don't forget the further from perpendicular a strand is the more tension on the strand.

Bridges are able to hold so much weight because of the way they are built and the tension that holds them together

NO THERE IS NOT! It is Apples to Apples! That's it! The game is so much fun!
