My apologies for not understanding you comment, I appreciate the time.

OK, So solved this with the help of a couple others. The rotating reel has an arm attached to it that puts pressure on a a cylinder. We now the dimensions of the reel as per above and the surface area of the cap of the cylinder and the current pressure the cylinder is developing. We also know...

I actually did it wrong, the reel acts as a fulcrum, so there is some mechanical advantage. I know the actual force pulling on the wire is between 50klbs and 72klbs, per the load attached.

Need a little assistance, and yes I should know how to answer this but... The project is from an Oil and Gas system. Deadline anchor and load cell. a reel has wire rope on it that acts on an arm that puts pressure on a load cell. I'm trying to back calculate the force in lbs on the wire rope...

Confused, why subract one inch? the total diameter would be 2 X Rope diameter + Root Drum Diameter

Simple design only, not for commerical review/standards. We have a motor connected to a gear box (1:1) ratio, connected to a drum that has wire rope wrapped half way across the drum on the root layer (1st layer). What I am expecting is that that if the drum had a root diameter of 100 inches...

I'm doing some work were its necessary to calculate the force acting on a drum via a wire rope. If I have a known weight acting on the rope already and I want to back calculate the minimum torque necessay for a motor connected to that drum to hold that load, do I add the diameter of the rope to...

Jobrag, I have a question please. If this was an application with a rope wrapped around the drum, would we not consider the diameter of the rope in addtion to the radius of the drum to back calculate the force necessary?

Assuming no losses due to efficiency :)

Gentlemen please. I am trying to find out how much a motor can lift through a gear reduction to a drum connected a block and tackle assembly. The motor can develop 16K N-M of torque, through a gear reduction of 7.51, turning a drum having a diameter of 1 meter, using 0.0508 meter rope. there...
