Question:

How many independent elastic constants exist for an anisotropic linear elastic material?

Inactive
Harsh B.
Answer:

The fourth-order stiffness tensor contains at most 81 elastic constants, but since it has both major and minor symmetries, this number reduced to 21 for a general anisotropic linear elastic material. If the material is isotropic, the number of constants further reduces to only 2.

Question:

Find the limit of ln(3t)/t^2 as t approaches infinity.

Inactive
Harsh B.
Answer:

First, we observe that as t approaches infinity, both the numerator and denominator approach infinity. This means we can use L'Hospital's rule. Taking derivatives of both the numerator and denominator: (1/t)/(2*t) = 1/(2*t^2) Now as t approaches infinity, we see the expression goes to zero.

Question:

You are in a canoe in a pool. You mark the water level at your side. You have a rock in the canoe. You throw it overboard and it sinks to the bottom. What happens to the water level?

Answer:

The key concept here is buoyancy, which is proportional to the volume of fluid displaced. When the rock is inside the canoe, the volume of the water displaced is [(M+m)/w] where m = weight of rock, M = weight of canoe, and w = density of water. When the rock is thrown overboard, the volume of the water displaced is [M/w + m/r] where r = density of rock. Subtracting these two equations, we find that the volume change of the displaced water is [m/w - m/r]. Since the rock sinks, its density is greater than that of water, i.e. r > w. This means the volume change is positive and more water is displaced when the rock is in the boat. Therefore, when the rock is thrown overboard, the water level falls.
