A round steel shaft is subjected to a concentrated moment M=1000 lbf.in at point B, which is located at distances a=8,b=9 in fro

m either end. Modulus E=30 Mpsi. The shaft is mounted on bearings that cannot tolerate a slope in excess of θ=0.002 rad. The bearings can be assumed to behave as simple supports. Calculate: ∙ The minimum diameter d required so that the slope at the supports does not exceed the limit.

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 parallel-plate capacitor has square plates that have edge length equal to 1.20×102cm and are separated by 1.00 mm. It is conne
lora16 [44]

Answer:

Energy stored in the capacitor will be 1.835\times 10^{-6}J

Explanation:

We have given edge length of capacitor = 1.2\times 10^2cm=1.2m

So area A = 1.2×1.2 = 1.44 m^2

Separation is given as d  1 mm = 10^{-3}m

We know that capacitance is given by C=\frac{\epsilon _0A}{d}=\frac{8.85\times 10^{-12}\times 1.44}{10^{-3}}=12.744\times 10^{-9}F

Voltage is given as V = 12 volt

We know that energy stored is given by E=\frac{1}{2}CV^2=\frac{1}{2}\times 12.744\times 10^{-9}\times 12^2=1.835\times 10^{-6}J

The following chart provides the pH of some common foods. How many would be considered basic?
Yuri [45]

The ones with pH greater than 7

Explanation:

A pH scale is a scale for expressing the level of acidity or alkalinity of aqueous solutions.

This scale is called a pH or pOH scale. The pH is the common one.

pH of a solution is the negative logarithm to base 10 o the hydrogen ion concentration of the solution.

  • The scale ranges from 1 through 14.
  • An acidic solution has a pH value less than 7. Neutral solutions have pH of 7 and basic solutions have pH greater than 7.

Which satellite has the greatest gravitational force with Earth?
EastWind [94]

Answer:

Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320.

Explanation:

The universal law of gravitation states that the force between two objects in the universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

We have to choose the satellite having greatest gravitational force with earth. In all options the distance from the earth is same i.e. 320 km. So, we have to select the satellite having maximum mass because the mass of the earth is constant.

Hence, the correct option is (D) " Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320 ".
