Calculating Moments: Forces on a Ratchet Wrench

[MienTommy]

Homework Statement

Two 20 lb forces are applied to a ratchet wrench down at A and up at B to loosen bolt β. Find the sum of the moments of the two forces about the axis (x) of the bolt.

Homework Equations

What are the moments at point A, B, and Q?
How do I find the moment about the x-axis and not at the bolt β?

The Attempt at a Solution

Not sure how to set up the problem because of the different pivots Q and B which are angled.

First step: What torque is transmitted down the 8" wrench extension?
Have you studied torques as vectors?

 

[MienTommy]

Yes I believe I have, but we call them moments? Could I just find the moment on the 8" wrench extension and project it on the x-axis by multiplying it by cos(45) to find the answer?

 

[insightful]

Yes, I believe that's right.

 

[MienTommy]

This is my attempt at the problem, I feel like it is wrong because of my Force vector.

Unfortunately, I can open, but can't read your attachment. What is the moment in the wrench extension?
