A disk between vertebrae in the spine is subjected to a shearing force of 640 N. Find its shear deformation taking it to have the shear modulus of 1.00 109 N/m2. The disk is equivalent to a solid cylinder 0.700 cm high and 4.30 cm in diameter.

3.08*10^-6 m

Explanation:

Given that

Total shearing force, F = 640 N

Shear modulus, S = 1*10^9 N/m²

Height of the cylinder, L = 0.7 cm

Diameter of the cylinder, d = 4.3 cm

The solution is attached below.

We have our shear deformation to be 3.08*10^-6 m

when the velocity of a mass on a spring is zero, the acceleration is at a maximum .

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
