Homework Statement
The Attempt at a Solution
for part 1:
i figured that this structure is not in static equilibrium. once load "P" is applied, the roller at "D" will function as a fulcrum and ABC will lift (make an angle with the horizontal).
is that assumption correct?
based on what i assumed:
i assumed:
2 reactions at "A", -Ax and -Ay
0 reactions at B
1 reaction at "D", Dy
i summed the moments about "D"
(clockwise moment is negative)
(-PL)+(Ay4L)=0
Ay= -P/3L ========================
Sum of forces in Y direction = 0:
Ay+Dy-P= 0
Dy= P-Ay
after substituting for Ay:
Dy=(3PL+P)/(3L) =========================
i don't know how to find Ax.
is what i did so far correct?
help please
