Oh ok thank you I have figured it out now😊👍

The molecule is p-phenetidine

Thank you for helping:biggrin:

Since L is conserved If I(final) is increased by a factor of 3, the w(final) is decreased by a factor of 3 so that L(final) = L(initial) I(initial)*w(initial) = I(final)*w(final) x*9.4 rad/s = 3x * w so w(final) = 9.4 rad/s / 3 = 3.1 rad/s Is that correct?

Like I = mr2? w = Δθ/Δt I didn't get what you mean by quantities

I have no idea how to go about this. Any help would be appreciated thanks :) Edit: I converted the 1.5 rev/s to rad/s = 9.4 rad/s

Oh so a = v/t = 8/4 = 2m/s2 (?) F = ma = 60*2 = 120N

I derived the formula for t but don't know how it works Δt = p/F I got p = mv = 60*8 = 480kgms-1 Δt = 480/120N = 4s Is that correct?

Could you please tell me where the UTS and Yield stress would be on my graph?

The substance being tested is Polyethylene. I have uploaded a picture of the fracture and the graph as jpg

Help would very appreciated. Also I am new to this website so if something seems wrong please tell me :)

Ahh ok ok thank you so much :)

Yeah I just need help graphing it. That was the only information I was given.

Here is my working in case it helps :)Ignore the v = 0.6/0.0001 = 6000m/s
