Problem 43P

(II) A 15-cm-long tendon was found to stretch 3.7 mm by a force of 13.4 N. The tendon was approximately round with an average diameter of 3.5 mm. Calculate Young's modulus of this tendon.

Step by step Solution

Step 1 of 2

L0=15cm=0.15m (the original unstreched length of the tendon)

ΔL=3.7mm=0.0037m (change in length of the tendon under stress)

F=13.4N (the force in tendon causing the stress)

D=8.5mm=0.0085m (the diameter of the tendon)

R=D/2=0.0085/2= 0.00425m (the radius of the tendon)

E=? (young`s modulus of the tendon)
