The gure shows the stress-strain curve for a material. The scale of the stress axis is set by s = 330, in units 0f10 N/m2. What are {a} the Young's modulus and (b) the approximate yield strength for this material? Assume a = 0.0090. cf : 3' a. Z 1: DC 00 s 26' Strain {a} Number n Units v {b} Number n Units v After a fall, a 110 kg rock climber finds himself dangling from the end of a rope that had been 18 m long and 11 mm in diameter but has stretched by 3.1 cm. For the rope, calculate (a) the strain, (b) the stress, and (c) the Young's modulus. (a) Number i Units (b) Number i Units (c) Number Units V
