A 19

cm

long tendon was found to stretch 4.5

mm

by a force of 11.3

N

. The tendon was approximately round with an average diameter of 8.2

mm

.

Calculate the Young's modulus of this tendon.

Young's modulus of this tendon is .

Explanation:

Given that,

Length of the tendon, l = 19 cm

It is stretched by 4.5 mm,

Force, F = 11.3 N

Average diameter, d = 8.2 mm

Radius, r = 4.1 mm

The formula of Young's modulus of this tendon is given by :

So, the Young's modulus of this tendon is . Hence, this is the required solution.                

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
