The solid spindle ab is made of a steel with an allowable shearing stress of 12 ksi, and sleeve cd is made of a brass with an al

Keith_Richards [23]

solution:

solid spindle ab:

c= 1/2ds = ½(1.5) = 0.75in.

j= π/2c1= π/2(0.75)2 = 0.49701 in4

jmax = Tc/j

tab=jtal/c = (0.49701)(12)/0.75 = 7.952

sleeve cd = c2 = 1/2d2 = ½(3.0) = 1.5in

j = π/2(c24 – c14) = π/2(1.54-1.254) = 4.1172 in4

tab = jtl/c2 = (4.1172)(7)/1.5 = 19.213 kip.in

Simplify the expression 6C2

iVinArrow [24]

Answer:

$^6C_2=15$

Step-by-step explanation:

Recall the formula:

$^nC_r=\frac{n!}{(n-r)!r!}$

We apply this formula to simplify $^6C_2$

This implies that:

$^6C_2=\frac{6!}{(6-2)!2!}$

$^6C_2=\frac{6!}{4!2!}$

$^6C_2=\frac{6\times5\times4!}{4!\times 2\times1}$

This simplifies to

$^6C_2=\frac{6\times5}{2\times1}$

$^6C_2=\frac{3\times5}{1\times1}=15$

Which of the

alisha [4.7K]

Given:

The inequality is:

$x>111$

To find:

The x-values that are the solutions to the given inequality.

Solution:

We have,

$x>111$

It means all the real numbers greater than 111 are the solutions to the given inequality.

$97$ , so 97 is not a solution.

$101$ , so 101 is not a solution.

$119>111$ , so 119 is a solution.

Therefore, the correct option is C.
