Answer:
k = Y*A/L
Step-by-step explanation:
We can apply the Law of Hooke in order to explain the problem.
If we define k = F / ΔL and the Y = S / δ
Where S is the uniaxial stress: S = F / A <em>(i)</em>
and δ is the strain: δ = ΔL / L <em>(ii) </em>
ΔL is the change in length
we can combine the equations i and ii as follows
Y = (F / A) / (ΔL / L) = (F * L) / (A * ΔL) <em>(iii)</em>
if k = F / ΔL the equation <em>iii</em> results
Y = k * (L / A) ⇒ k = Y*(A / L)
Answer:
6/13
Step-by-step explanation:
since there are only 13 cards numbered 1 through 13, we have to count how many of these numbers are even.
1 <u>2</u> 3 <u>4</u> 5 <u>6</u> 7 <u>8</u> 9 <u>10</u> 11 <u>12</u> 13
Once you've figured out how many even numbers there are - in this case, there are 6 of them - then you put that number over the total number of cards, which is 13. So, you would get 6/13, which also happens to already be in simplest form.
hope this helps :)
