Homework Help: Math/physics

Posted by Era on Wednesday, September 23, 2009 at 3:36pm.

Christian is making a Tyrolean traverse. That is, he traverses a chasm by stringing a rope between a tree on one side of the chasm and a tree on the opposite side, 25 m away. The rope must sag sufficiently so it won't break. Assume the rope can provide a tension force of up to 27 kN before breaking, and use a "safety factor" of 10 (that is, the rope should only be required to undergo a tension force of 2.7 kN) at the center of the Tyrolean traverse.

Determine the distance x that the rope must sag if it is to be within its recommended safety range and Christian's mass is 74.0 kg.

If the Tyrolean traverse is incorrectly set up so that the rope sags by only one-fourth the distance found in part A, determine the tension force in the rope in newtons.

Will the rope break?

How can you do this problem? I can't even start it.
