A nonuniform, horizontal bar of mass m is supported bytwo massless wires against gravity. The left wire makes an angleϕ1 with the horizontal, and the right wire makes an angleϕ2. The bar has length L
. (Figure 1)

Part A
Find the position of the center of mass of the bar,x
, measured from the bar's left end.
Express the center of mass in terms of L
, ϕ1, and ϕ2. Note that any trigfunction entered in your answer must be followed by an argument inparentheses.
