A iniform rod of length 2 a and weight W

is smoothly pivoted to a fixed point

at A . A load of weight 2 W is attached

to the end B . The rod is kept horizontally

by a string attached to the midpoint

D of the rod and to a point C vertically

above A .

If the length of the string is 2 a, find,

in terms of W, the tension in the

string and the magnitude of the

reaction at the pivot .
