## Question

###### Bob 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, Fig. 4-65. Assume the rope can provide a tension force of up to 29 kN before breaking, and use a "safety factor" of 10 (that is, the rope should only be required to undergo a tension force of 2.9 kN). (a) If Bob's mass is 72.0 kg, determine the distance $x$ that the rope must sag at a point halfway across if it is to be within its recommended safety range.

Assume the rope can provide a tension force of up to 29 kN before breaking, and use a "safety factor" of 10 (that is, the rope should only be required to undergo a tension force of 2.9 kN). (a) If Bob's mass is 72.0 kg, determine the distance $x$ that the rope must sag at a point halfway across if it is to be within its recommended safety range. ($b$) If the rope sags by only one fourth the distance found in ($a$), determine the tension force in the rope. Will the rope break?
