A nylon rope used by mountaineers elongates 1.10 m under

the weight of an 65.0-kg climber. A nylon rope used by mountaineers elongates 1.10 m under

the weight of an 65.0-kg climber. If the rope is 45.0 m in length and 7.0 mm in diameter, what is

Young’s modulus for this material? (Express your answer using two

significant figures).

the youngs modulus is calculated by the ratio of stress by

strain

stress = perpendicular load per unit area,

strain is elengation per unit length

(65.0kg) (9.81 ) (45.0 m) T (3.5 x 10-3m) (1.10m) = 6.8 × 108 Pa
