ank_gl from what I have read your approach seems to be correct! Page 7 of this seems to derive the equation as well; http://ocw.mit.edu/NR/rdonlyres/Physics/8-01TFall-2004/84DD1138-93A4-47E0-8F54-CB45EBE8351D/0/exp05b.pdf"
Thanks for leading me in the right...
Sorry I keep calling them rollers. Pretty much these cylinders are still and they have a surfance roughness, the rope moves backwards and forwards through the cylinders hence abrazing the rope!
I need to find the forces in the pins holding the cylinders still and the power of the motor...
Thanks a million for the replies.
Sorry should have specified! The rollers stay still and the rope is moved back and forwards through the rollers.
The rollers are held in place by pins on either side I just need to find the shearing force in the pin which I assume is releated to the...
Hey,
Got some rope running through four stationary cylinders (pic below)! Now if the rope on the left hand side is pulled down with let's say 100N, I would just like to find out the force on each cylinder.
common sense tells me that the force on all four cylinders will be 100N in alternating...
Hi,
I have the following formula: brake power = 2(pi)NT
I also have the following figures: RPM (instant) = 3550rpm and N° of cycles over 30secs = 880.
The engine is four stroke-one cylinder. Just wondering how do I covert the number of cycles to RPM?
I have divided by 0.5 because it was for...

Hey guys,
I am a bit stuck on this prolbem. When it says identify the characteristic physical scales is this referring only to the length scales (l, h, b)? or is U, gravity, density and viscosity included as well?
Now the only two...
