Information
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.
All of the images in this quiz have been created using vRigger (see http://www.vRigger.com for details).

The winch being mounted does change things, hadn’t expected that. Nice job Richard, Thanks.
