Answer:
dmin = 1.4374in
Explanation:
In the question, it says slope at the support should not exceed the limit. When such a sentence is given always use the <u>maximum value of the property</u>. So here the maximum moment of inertia is used.
θ₁ = Pb(l² – b²)/6lEI
0.002 = 1000 x 8 x (142 - 82)/6 x 14 x 30 x 10⁶ x I₁
I₁ = 0.209523 in⁴
θ₂ = Pab(2l - b)/6lEI
0.002 = 1000 x 6 x 8 x (28 - 8)/6 x 14 x 30 x 10⁶ I2
I₂ = 0.190476 in⁴
<u>For design point of considerations, taking higher value of M.I, which is I₁</u>
I₁ = 0.209523 = (π/64) x d⁴
d⁴ = 4.2683
dmin = 1.4374in
. a positive charge always moves from a higher potential to a lower potential is right answer.
Answer: C). Light rays are bent by the water in the glass
It refracts the light
The bending of a light moving from one end to another is called refraction
<span>It starts to cool down in Arizona in mid-October. The weather remains good in October- April and the heat tends to break in mid of October. The time when it is coldest in Arizona in December or January. However, it's too hot in the month of July and Rain becomes common in Spring season.</span>
