Homework Statement
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 tension s in the other three strands are as follows:
strand 1: 21.00 mN [22.00°E of N]
strand 2: 16.00 mN [66.00°E of S]
strand 3: 18.00 mN [44°W of S]
