5. A spider builds its web in a window frame that is lying on the ground. It is supported by four main strands. Calculate the force of tension in strand 4 assuming the web is stable. The tensions in the other three strands are as follows: strand 1: 21 mN [N 20° E] strand 2: 16 mN [S 60° E] strand 3: 18 mN [S 40° W]
