I can do this question by taking moments about A but I dont get the same answer by taking moments about B.
i.e. M(B): Clockwise = anticlockwise
Ra x 0.8 = 60cos40 x 0.5 + 60sin40 x0.1
Ra = 33.55
vertically Ra x sin40 = 29.1N
But taking moments about A gives vertical support as 50.5N
Thanks in advance
