Answer 1

2) Strain change in length Actual length = AL L 2.2x10²m 14m 0.00157 strain has unitless no unit. It is stress 416 A s-radius D-diameter z TO Z mg TDI 4 mg TD2

Stress U 4 x 97 97 kg x 9.8 m/s² T * (8.3x10-3m)? 1.757x10 Nm Youngs Modulus stress strain 7 1.757x10 Nm² 0.0015 = 1.12x10 Nm -2
