The 25-kg bar has a center of mass at G. If it is
supported by a smooth peg at C, a roller at A, and cord AB,
determine the reactions at these supports.

bro THINKS YOU LIKE holy every question i search up you are there to help, thx fr bro.

[@lotachukwuuyanne9366]

How come you didn’t include the horizontal component of G in the summation of X forces?

[@amroiblasi1318]

why you didn't put a component of X for Wight when you calculate the summation of x?

[@efrenacevedo4534]

Is there a way you can do a video for number 5-38?

[@tlnwlf6036]

Are the reactions from C included in the Free Body Diagram?

[@efraimjosua2107]

can u explain the normal force at the connection a and the bar

[@Relsie]

It's the convention for rollers in 2-D equilibrium problems, the reactive force for a roller is perpendicular to the surface. It's a similar concept of the normal force in more fundamental physics problems (car rolling down hill, for example)
