to figure out the Ay and Ma reactions, i tried to find the effect of the 9kn/m force. i did this by integrating:
integral from 0 to 8: 9x
i found this to be 288kn
for the moment caused by the 9kn/m force:
integral from 0 to 8: 9(x^2)
i found this to be 1,535kn*m clockwise
i then added this to the moment about A caused by the 100kn force in the positive x direction:
(100kn)(12m) + 1,536kn * m= 2,736 kn*m
so my answer for the first part would be:
reactions:
Ax= -100kn
Ay= 288kn (in positive y direction)
Ma= 2,736 kn * m counterclockwise.
am i correct?
