Question

Find three different solutions of the each of the following equations. 1.(3x+4y=7) 2.(y=6x) 3.(2x-y=7) 4.(13x-12y=25) 5.(10x+11y=21) 6.(x+y=0)​

Answer 1

Step-by-step explanation:

Longitudinalstress=

crosssectionalarea

force

\ \bf Force = 100kN \: or \: 10000N Force=100kNor10000N

\bf Area = 3.14 × {10}^{ - 4} {m}^{2}Area=3.14×10

−4

m

2

\ \bf Longitudinal \: stress = \frac{10000}{3.14 \times {10}^{ - 4} } Longitudinalstress=

3.14×10

−4

10000

\ \bf = \frac{100}{314 \times {10}^{ - 4} } =

314×10

−4

100

\bf \ = \frac{ {10}^{2} }{314 \times {10}^{ - 4} } =

314×10

−4

10

2

\bf \ = \frac{1}{314 \times {10}^{ - 2} } =

314×10

−2

1

\bf = \frac{1}{3.14}=

3.14

1

\bf \ = 0.3(approximately) =0.3(approximately)

∴ Stress acting on the rod = 0.3 Pa
