Which expression would be easier to simplify if you used the commutative property to change the order of the numbers?
Cerrena [4.2K]

Answer: A. 30+(-12)+70

Step-by-step explanation:

Commutative property of addition is given by : a+b = b+a , where a and b can be any expression of real numbers.

It basically changes the order of the so that simplification of any expression becomes easier.

In A. we use this property as

30+(-12)+70 = 30+[(-12)+70]

= 30 + [70+(-12)]  [we switched order of (-12) and 17]

= 30+70-12

= 100-12

= 88

The rest of the expression already arranged accordingly, there is no need to apply commutative property to change the order of the numbers.

So the correct option is A. 30+(-12)+70.

A cylindrical 2014-t6 aluminum alloy bar is subjected to compression-tension stress cycling along its axis; results of these tes
Pani-rosa [81]

Complete part of Question:

Assume a factor of safety of 3.0

The Maximum stress versus logarithm of the number of cycles to fatigue failure curve for 2014-T6 Aluminium bar is attached to this solution

Answer:

The maximum allowable load amplitude is 6403.33 N

Step-by-step explanation:

diameter of the bar, d = 12 mm

d = 0.012 m

Cross sectional area of the bar, A = πd²/4

A = π*0.012²/4

A = 0.000113 m²

From the Maximum stress versus logarithm of the number of cycles to fatigue failure for 2014-T6 Aluminium bar attached to this solution;

At 10⁷ cycles, Maximum stress, S = 170 MPa

S = 170 * 10⁶ Pa

Factor of safety, N = 3.0

The tensile stress is given by the formula:

\sigma = S/N\\\sigma = \frac{170 * 10^{6} }{3} \\\sigma = 56.67 * 10^{6} N/m^{2}

The tensile stress is also given by:

\sigma = F/A\\\sigma = F/0.000113

F/0.000113 = 56.67 * 10⁶

F = 56.67 * 10⁶ * 0.000113

F = 6403.33 N

The maximum allowable load amplitude is 6403.33 N
