An adventurous archaeologist crosses between two rock cliffs by
slowly going hand-over-hand along a rope stretched between the
cliffs. He stops to rest at the middle of the rope . The rope
will break if the tension in it exceeds
2.55×104 N , and our hero's mass is
87.6 kg .
1. If the angle between the rope and the horizontal
is θ = 11.1 , find the tension in the rope.
2.What is the smallest value the angle θ can have if
the rope is not to break?
