For safety in climbing mountaineers use a nylon rope that is 50m long (L) and 0.1 m in diameter. When supporting a 900 N climber the rope stretches 1.6 m (AL) under tension. Find the Young's Modulus (Y) for the nylon rope.

Answer 1

same as the last one

Answer 2

Y= [(Force)(Length of rope)]/Area*(change in rope length)

Area= [(pi)(diameter^2)]/4

Answer 3

I can't understand
