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 frictionless 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.
