I am designing these brackets on a ventilation system to hold filters that my company stocks regularly. The vent is about 49.5"x49.5" and the filters are about 23.5"x23.5". Placing 4 filters in this square vent leaves about 1.25" on each side. I have designed the brackets so that they block the...
So what I do is break up the pulley into sections and add up the tensions (T) right? With the tensions from each section I can get the ratio? Is this correct? I re-drew the drawing with my work on it. 9T:1T is my answer I just need someone to check that.
A guy at work gave me this drawing I have attached and asked me to find the pulley ratio. Do I need any other information such as rope lengths, pulley diameters, or load? I traded in my machine design book and don't remember exactly how to calculate the ratio. Is there anything else I can...

I think it is used in an ideal gas formula and is used also in calculating for properties in the otto cycle...I was just curious because I had a homework problem where the answer guide used Vr but the text did not use Vr in any of its examples even though it had a list of Vr values. I don't know...
what is Vr... I know how to get Vr from my text but not sure what it is and what its used for...Im trying to find values for internal energy for an otto cycle question...im working on EES but only know how to get the values for Vr from the text
