Question

A 15.4 cm long tendon is found to stretch 2.63 mm when a force of 15 0 N is applied to it. If the tendon is round and as an average diameter of 6.94 mm, calculate the Young's modulus of this tendon Number IUnits

Answer 1

Answer 2

SOLUTION :

Young’s modulus 

= Stress / strain 

= (Force / Area) / (Stretch / Length)

= Force * Length / (Area * Stretch)

= 15.0* (15.4/100) / ((pi/4 * (6.94/1000)^2) * (2.63/1000))

= 2.322*10^7 N / m^2 9ANSWER)
