RopeLab Quiz 2: Tripods & Resultant Forces

This quiz presents a series of short questions looking at the forces in a range of tripod configurations.

For all questions assume that the system is static.  In other words, nothing is moving, tensioned ropes are shown as straight, non-tensioned ropes are shown with slack, and ropes in winches are locked off.
