The equation x^3-5x=59 has a solution between 4 and 5. Use a trial and improvement method to find this solution. Give your answe

vodomira [7]

Answer:

The answer is "4.3".

Step-by-step explanation:

Given:

$\to x^3 - 5x - 59 = 0$

When $x = 4.1:$

$\to f(4.1) = (4.1)^3 - 5(4.1) - 59 = -10.579$

When $x= 4.2:$

$f(4.2) = 4.2^3 - 5(4.2) - 59 = -5.912$

When $x = 4.3:$

$\to f(4.3) = -0.993$ (closer to 0)

$\to f(4.4) = 4.184$

It changes the sign so, the root lies in 4.3 and 4.4.

When $x = 4.35:$

$\to f(4.35) = 1.563$

When the root is closer to 4.3 than 4.4 So, 1.563 is closer to zero than 4.184.

When $x = 4.32:$

$\to f(4.32) = 0.0216$ close to zero.

So the answer is 4.3 to 1 decimal place.

Two gears in a 3: 1 ratio gearset and with a diametral pitch of 4 are mounted at a center distance of 6 in. Find the number of t

Ivahew [28]

Answer:

Number of teeth on pinion = $N_{p}$ = 12

Step-by-step explanation:

Given:

Gear ratio = 3 : 1 = 3

Diametral Pitch = P = 4

Center distance = c= 6 in

No. of teeth on Pinion = $N_{p}$ =?

Gear ratio = $\frac{ Number. of. teeth. on. gear}{ Number. of. teeth. on. pinion}$ = $\frac{N_{g} }{N_{p}}$ = 3

As Gear ratio = 3, so

Diameter ratio = $\frac{d_{g} }{d_{p}}$ = 3

<em>(Note : Diameter Ratio = Gear ratio )</em>

$d_{g} =3d_{p}$ <u> </u><em><u>Equation 1</u></em>

Center Distance = c = $\frac{d_{g} + d_{p}}{2}$ = $d_{g} + d_{p}$ = 2 (c)

$d_{g} + d_{p}$ = 2 (6) = 12 in

substitute $d_{g}$ from equation 1, here

$3d_{p} + d_{p}$ = 12

$4d_{p}$ = 12

$d_{p}$ = $\frac{12}{4}$ = 3

$d_{p}$ =3in

Now : Diametral Pitch =P= $\frac{N_{p} }{d_{p} }$

$N_{p}$ = $d_{p}(P)$

$N_{p}$ = 4 (3)

$N_{p}$ = 12

Which are the number of teeth on pinion
