So ill add both of these together to get the complete mass of the object, Should i then treat it as AO and then OB or do you wrok with the whole object i.e can it be two separate ladders leaning against a point or not?

Does this mean that AO will have a mass of (2l/3)(p) and OB will have a mass of (l/2)(p)?

Thanks for the quick response. I have thought of that but how do I go about finding the masses without any information besides that AO = 2l/3, OB=l/2 and that 30o degree angle at A. With the free body diagram, Ill have downwards force(gravity), a force pushing back on A, anti-clockwise force...

So this is the question that is given The right-angle uniform slender bar AOB has mass m. If friction at the pivot O is neglected, determine the magnitude of the normal force at A and the magnitude of the pin reaction at O. Now I don't really know where to start whit this or what to do at...
