Question

A 50-m steel tape is standard at 0°C. What is the actual length at 28°C? Linear coefficient of expansion is 11 × 10-6/°C.

Answer 1

it's \[50*(1+(28-0)*11*10^{6})\]

Answer 2

What's wrong with OpenStudy equation? I typed in ^-6 and it appeared ^6. Sighhhh

Answer 3

@NgoKimPhu
You should type ^{-6}

Answer 4

@NgoKimPhu how did u come up with that eqn?

Answer 5

@LastDayWork pls help :)

Answer 6

@ankitshaw help ! :)

Answer 7

@zaisav
Do you know the equation for thermal expansion ??

Answer 8

correction: linear coefficient of expansion is 11 x 10^-6 / degreeC

Answer 9

@LastDayWork i think its \[\Delta L = \alpha L \Delta T\]

Answer 10

@hassy help

Answer 11

@Emineyy help

Answer 12

@zaisav
Will you please stop tagging people ?
& can you find ΔL for this case ??

Answer 13

im not sure. i tried using the formula and i substituted the alpha, L, and delta T, but idk in the delta L

Answer 14

The final answer will be (L+ΔL)
So find ΔL from the formula you posted & add it to L

Answer 15

ok i get it now. thank u so much :)
