Homework Statement
I got part A of the problem right. I am stuck on part B. As you can see, they ask for the reactions at B, D and E.[/B]
Homework Equations
The Attempt at a Solution
OK, here's the book's the answers: at D, 350N k. At E, -100Nk, and at B -250N k.
So, we have a 50Nm torque applied at the shaft along axis x. At the edge of the yoke, the force applied would be 50/d, where d is an unknown quantity (1/2 the width of the yoke).
Wouldn't we want to find the reactions at D, E and B by starting from the edge of the yoke?
Then, for the reaction at D, we'd have an equation like this:
-(50/d)j x (-dj + .08i)
The d values cancel conveniently, yielding a value of 4Nk, which disagrees with the book.
Where am I making a wrong turn?
All help appreciated...thank you :^)
