Two identical, uniformbeams weighing 260 N each areconnected at one end by a frictionlesshinge. A light horizontal crossbarattached at the midpoints of thebeams maintains an angle of 53.0°between the beams. The beams aresuspended from the ceiling by verticalwires such that they form a “V”. (a) What force doesthe crossbar exert on each beam?(b) Is the crossbar under tension orcompression? (c) What force (magnitude and direction) does the hingeat point A exert on each beam?

Question
Two identical, uniform
beams weighing 260 N each are
connected at one end by a frictionless
hinge. A light horizontal crossbar
attached at the midpoints of the
beams maintains an angle of 53.0°
between the beams. The beams are
suspended from the ceiling by vertical
wires such that they form a “V”
. (a) What force does
the crossbar exert on each beam?
(b) Is the crossbar under tension or
compression? (c) What force (magnitude and direction) does the hinge
at point A exert on each beam?
