Calculating the Mechanical Advantage in a Simple System

This video comes from our Conversations in Rigging eCourse with Richard Delaney.
In this course, Richard dives into subjects ranging from calculating mechanical advantages, fallen worker recovery, high angle systems, and the friction to be aware of within them, along with the anchor systems used to rig high angle systems.

That finally explained why exactly pulleys can multiply mechanical advantage. I've only been taught that it simply does multiply it. Great explanation.

[@josepskoolacc8161]

my left ear enjoyed this

[@jeaninechen9052]

I want to add a pully system to raise the end of my batting cage net. Any suggestions? I was going to use 3 pullies 2 on the end and try to run the 2 ends to the middle and this will connect to a locking wench so kids can pull it up down? any advice appreciated.

[@WritersOnTheWall]

I know this is a really old video but Canyon do this in reversecan I pull the rope from the center pully to increase the height pulled. I want to move something 18 inches with as small a linear actuator as possible

[@metalrooves3651]

i am rigging an 18 ton crane tomarrow,called reeving the block...for every "part" that is verticle cable,except the redirect,we can multiply by 2?..so a 4 part would be times 4?...so for every unit pulled out,1/4 of a unit is the lift???THIS IS THE SIMPLE CALCULATION im looking for!! I have seen 10 part lines!! Why isnt this SIMPLE thing explained??AND also, not addressed here is can there be odd numbers of "parts" like 3 or 7?? by deadmanning the end at the load instead of the top??

[@richardcoble9498]

U can put one at the bottom aftergoing up or starting going dn then up the to load from load to last support and the bottom pulley is called a " snatch block" i think thats what its called. Funny to me snatch block......

[@RulgertGhostalker]

but if your load pulley there was fixed to the floor, and you were developing a downward force, it would be a 3:1

[@capuccinolight]

Again, just count tensions ONCE and don’t mess up

[@andycapp8843]

Javier…..is there a link to the video you made that illustrates the system more clearly?

[@johnstrawb3521]

@@andycapp8843 TRY "Mechanical Engineering: Particle Equilibrium (11 of 19) Why are Pulleys a Mechanical Advantage?" Very, very clear. Great channel. Best wishes.

Looks good but the music is louder than the vocal. Couldn't follow the advice. Sorry!

[@matthewhernandez3435]

Why is it called the “T” method?

I have not understood

There is no sound. I can’t hear the person speaking

I'm sorry to be critical, but as a California State instructor for RS1, Con Space, trench etc., I think this is a poor video describing M'A's. The footage and video quality is great but it is could be better explained. Check out "smarter every day" who has made a fantastic video describing M/A's.

I think you need one unit of intention....get on with it man

Can't freaking people speak up on this

I’m sure it’s a good video but you can’t hear anything but the background music

I can hear it just fine

Goes completely off the rails very early. Check out this fellows channel for a much better explanation: Michel van Biezen, including "Mechanical Engineering: Particle Equilibrium (11 of 19) Why are Pulleys a Mechanical Advantage?" ---I mean, look what this gentleman does here: he tells you at 2:53, whoops, this rightmost pulley doesn't actually contribute to the lifting!
