T=F/2sin
| |
A long Rope is suspended between a fixed object and a student (or two large students hold either end) |
| |
Pulling along the rope the student is unsuccessful at displacing the student at the end. Pulling at 90< easily wins the Tug of War. |

F=2Tsin T=F/2sin |
For small angles, 1/sin is large and for a small force F the tension required of the end student to resist being dragged is large. For example: at =10°, 1/sin=5.8 and T
3F to be stable. The end student is seldom that strong.
