## Homework Statement

in the attached picture are all the information needed to solve the problem.

The bent rod of a negligible weight is supported by a ball and a socket joint at A and a single journal bearing at B. End of D of the rod rests against a friction-less vertical surface. find the reaction forces at A and B.

## Homework Equations

sum of forces

sum of moments

Reaction forces:

Dx

By

Bx

Mbx

Mby

Ax

Ay

Az

## The Attempt at a Solution

moment around a line AB to get D

but then i am stuck!!

should i get the moment around line AD to get By and Bx? or there is even an easier way? double 2D perhaps?

I know i can use the moment around A and the equilibrium of forces in X,Y, and Z

but that will take the whole day, and i am sure the prof created the question in a way that will screw you up if you solve it using the equilibrium equations.

I would be grateful if you help me with this.
