I've got a torque wrench attached to a multiplier that is attached to a crows foot, and I'm trying to spec the input torque (at the wrench head) that will give us a corresponding output torque (at the crows foot).(adsbygoogle = window.adsbygoogle || []).push({});

I am aware of the calculations that need to be made when a crows foot (alone) is being used, but am struggling with the introduction of the multiplier.

This is what I came up with:

Given:

- Length of torque wrench is X

- Length of crows foot is Y

- Applied force is F

The equation for the moment about the crows foot reduces to: F*(4X + Y)

(please take a look at the attached pdf if you're interested in how I came up with this equation)

Am I on the right track?
