Thankyou Doc Al That has helped loads. I get the new speed to be 429 RPM which . If I could ask just one more question just to clarify things. I would just tlike you to explain where the "1" comes from in "KE1/KE2 = 1/0.8". Sorry if its obvious. Is it just how ratios are sorted out? thanks...

Thanks . I have ahd a look at the problem again and I am still abit puzzeled. I get the torque before the [press operation to be 202 Nm and after it has dropped to 162 Nm (the 20% drop). What I am not too sure about is does the torque in Nm equal the KE? If it does then i can use KE =...
