Chapter 7, Problem 2P

The member is supported by a square rod which fits loosely through the smooth square hole of the attached collar at AA and by a roller at B. The member is subjected to the forces F1 = 350 N , F2 = 450 N , and F3 = 600 N . Determine the normal reaction force of roller at B. Determine the components of the reaction force of the support at A using scalar notation. Determine the components of moment of the reaction at A using scalar notation.
