Explanation:
Formula to determine the critical crack is as follows.
= 1, 
= 24.1
[/tex]\sigma_{y}[/tex] = 570
and, 
= 427.5
Hence, we will calculate the critical crack length as follows.
a = 
= 
= 
Therefore, largest size is as follows.
Largest size = 2a
= 
= 
Thus, we can conclude that the critical crack length for a through crack contained within the given plate is .
Answer:
Explained
Explanation:
Lunar mountains are smoothly rounded rather than having sharp, pointed peaks because the lunar moons are formed because of the impact of asteroids and comets on its surface whereas the Earth mountains are formed because of the surface activity of volcanos, collision of land masses and activity of plate tectonics that is why they have sharp and pointed tops.
Answer:
This is very hard bit I think 6.3 my, I'm not shure.
Answer:
The maximum value of θ that will cause the block to remain stationary on the inclined surface is 21.8°
Explanation:
Given;
coefficient of static friction, μ = 0.4
for the block to remain stationary on the inclined plane, force pushing the block upward must be equal to the force acting downwards.
μR = mgsinθ
μmgcosθ = mgsinθ
μcosθ = sinθ
μ = sinθ/cosθ
μ = tanθ
θ = tan⁻¹(0.4) = 21.8°
Therefore, the maximum value of θ that will cause the block to remain stationary on the inclined surface is 21.8°
