Can someone help me :)

Solution :

Given :

L = 1 in

d = 0.75 in

D = 1 in

Fillet radius, r = 0.063 in

[tex]$K_{t_{bending}=\frac{\sigma_{FEA_{bending }}}{\sigma_{Nominal_{bending }}}$[/tex]

We know that :

[tex]$\sigma_{b} = \frac{32M}{\pi d^3}$[/tex]

[tex]$\sigma_{b} = \frac{32 \times (2998.63 \times 25.4)}{\pi (0.75 \times 25.4)^3}$[/tex]

    [tex]$=112.27 \ N/mm^2$[/tex]

[tex]$\sigma_{FEA} = 1.3 \times 10^8 \ N/m^2$[/tex]

         [tex]$=1.3 \times 10^8 \times 10^{-6}$[/tex]

         [tex]$=1.3 \times 10^2$[/tex]   MPa

         = 130 MPa

Therefore, the stress concentration factor is :

[tex]$k_t=\frac{130}{112.27}$[/tex]

   = 1.157922

Answer:

v_f = 2.9m/s

Explanation:

v_f = v_I + a(t)

v_f = 0.6m/s + 1.2m/s²(1.9s)

v_f = 2.88m/s

v_f = 2.9m/s

From the question we are told that:

Number of Turns [tex]N=332turns[/tex]

Radius [tex]r= 30cm[/tex]

Field Change [tex]B=56mt-29mt=27mt[/tex]

Time [tex]t=63ms[/tex]

Generally the equation for Magnetic Field is mathematically given by

 [tex]\frac{dB}{dt}=\frac{27*10^{-3}}{29*10^{-3}}[/tex]

 [tex]\frac{dB}{dt}=0.9T/s[/tex]

Generally the Flux at 332 turns is  mathematically given by

 [tex]\phi=N*A*B[/tex]

Generally the equation for Area of coil is mathematically given by

 [tex]A=\pi*r^2[/tex]

 [tex]A=\pi*(r*10^{-2})^2[/tex]

Since

 [tex]\phi=332*\pi*(\theta*10^{-2})^2*B[/tex]

Therefore

 [tex]\frac{d \phi}{dt}=332*\pi*(900*10^{-4}*\frac{dB}{dt}[/tex]

Generally the equation for emf Magnitude is mathematically given by

 [tex]E=\frac{d\phi}{dt}[/tex]

 [tex]E=332*\pi*(900*10^{-4}*0.9[/tex]

 [tex]E=84.5V[/tex]

Answer:

Current, I = 20 Amperes.

Explanation:

Given the following data;

Voltage = 40 V

Resistance = 2 Ohms

To find current flowing through the resistor;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Making current (I) the subject of formula, we have;

[tex] I = \frac {V}{R} [/tex]

Substituting into the formula, we have;

[tex] I = \frac {40}{2} [/tex]

Current, I = 20 Amperes.

Answer:

(D) 50 W​

Explanation:

Given the following data;

Mass = 5 kg

Force = 100 N

Distance = 60 N

Time = 2 minutes

Conversion:

1 minute = 60 seconds

2 minutes = 60 * 2 = 120 seconds

To find the power output required to push the box;

First of all, we would determine the work done in pushing the box.

Work done = force * distance

Workdone = 100 * 60

Workdone = 6000 Joules

Next, we find power output;

Power = workdone/time

Power = 6000/120

Power = 50 Watts

A.K.A. the coin is heavy, which is why it did not move with the paper

Answer:

Newton's First Law - Law of Inertia

Explanation:

Newton's First Law, the Law of Inertia mentions that an object at rest will stay in rest until acted by another force. The penny's inertia will cause it to fall directly down into the cup because the magnitude of external force applied by the card will be too meager to have a notable effect.

Answer:

The final velocity is 50 m/s.

Explanation:

Below is the calculation of velocity:

v = u + a*t

v = final velocity

u = initial velocity

a = accreleration

Since, u = 0, a = 10m/s^2, and t = 5 seconds. Now plug these values in the formula.

v = u + a*t

v = 0 + 10 x 5

v = 50 m/s

The final velocity is 50 m/s.

Answer:

0.09 kg

Explanation:

The details of boiling liquid are;

The rate of thermal energy absorption by the liquid, P = 450 W

The specific latent heat of vaporization, c = 2.7 × 10⁶ J/kg

The required information = The amount of liquid vaporized in t = 9 minutes

We have;

P = E/t

Where;

P = Power supplied by the heat source = The rate of absorption of thermal energy

E = The energy absorbed

t = The time

The energy absorbed in 9 minutes, E = P × t

∴ E = 450 W × 9 min × 60 s/min = 243,000 J

The heat required to evaporate 1 kg of liquid = The  specific latent heat of vaporization, c = 2.7 × 10⁶ Joules

The mass of the liquid evaporated by the energy absorbed, E, m = E/c

∴ m = 243,000 J/(2.7 × 10⁶ J/kg) = 0.09 kg

Therefore, the mass of the liquid vaporized by the energy absorbed at a rate of 450 W, in 9 minutes, m = 0.09 kg.

Answer:

12/11 Ω isvthe equivalent resistance of the circuit.

Answer:

21 m

Explanation:

Since the displacement from the door is 2 m West, we have our vector as -2i. The vector representing 14.0 m South is -14.0j. The vector representing 25.0 m East is 25.0i. The vector representing 11.0 m North is 11.0j. And, the vector representing 2.0 m West is -2.0i.

So, to get our position vector at the other location, we add all the vectors together.

So, r = -2i + (-14.0j) + 25.0i + 11.0j - 2i

= -4i + 25.0i - 14.0j + 11.0j

= 21.0i -3j m

Now, if we assume the position vector for the door is at the origin, we have r₀ = 0i + 0j m

So, our displacement from the door is r - r₀ = 21.0i - 3.0j - (0i + 0j) =  21.0i - 3.0j

So, the magnitude of the resultant displacement |r - r₀| = √(21.0² + 3.0²)

= 3.0√(7.0² + 1)

= 3.0√(49 + 1)

= 3.0√50

= 3.0 × 7.0711

= 21.2

Answer:

v = 6295.55 m/s

Explanation:

Given that,

The radius of a planet, [tex]r=5.32\times 10^6\ m[/tex]

The free fall acceleration of the planet, a = 7.45 m/s²

We need to find the tangential speed of a person standing at the equator.

Also, the centripetal acceleration was equal to the gravitational acceleration at the equator.

We know that,

Centri[etal acceleration,

[tex]a=\dfrac{v^2}{r}\\\\v=\sqrt{ar}\\\\v=\sqrt{5.32\times10^6\times 7.45}\\\\v=6295.55\ m/s[/tex]

So, the tangential speed of the person is equal to 6295.55 m/s.

Answer:

8.829 Joules

Explanation:

The potential energy of an object, is the energy it posses (the energy stored within the object) by virtue of its relative elevation or height, position, state, or arrangement

The potential energy of an object raised to a given height, P.E. = m·g·h

Where;

m = The mass of the object

g = The acceleration due to gravity, a constant ≈ 9.81 m/s²

h = The present height of the object

For the potato sack having a mass, m = 2 kg, and raised to a height, h = 450 cm = 0.45 m, we have;

The potential energy given to the potato sack, by raising its height, P.E. is given as follows;

P.E. = 2 kg × 9.81 m/s² × 0.45 m = 8.829 Joules

The potential energy given to the potato sack, P.E. = 8.829 Joules

The amount of work required to lift the 230 kg to a height of 3.5 m at  84% efficiency is 9391.67 J

This can be defined as the capacity to achieve a given task with little or no waste. Mathematically, it can be expressed as

Efficiency = (output / input) × 100

Work output = mgh

Work output = 230 × 9.8 × 3.5

Work output = 7889 J

Efficiency = (output / input) × 100

84% = 7889 / input

Cross multiply

84% × input = 7889

Divide both side by 84%

Input = 7889 / 84%

Input = 7889 / 0.84

Input = 9391.67 J
