Find the reactions exerted on the members by the supports.

2. Relevant equations

Sigma Fx = Net force acting on x axis = 0

Sigma Fy = Net force acting on y axis = 0

Sigma M = Net Moments = 0

3. The attempt at a solution

10N/m -> changes to 4N at centre acting downward so total force acting downward is 34N

the Sum of two y component of two forces from suppors then equals to 34N

If I set the regarding point to be the point on the left supports, then total moment is

30 x 0.2 + 4 x 0.6 - 50 - Fy x 0.8 where Fy is the y component of force from the right support. But this gives negative value for Fy which means that the supporting force from the right side support is downward. How can this be true?

Any problem with my steps?

I neglected Fx as there is no movement of bar and only force acting in x direction is the x component of supporting from left support and that should be equals to 0
