A uniform boom of length 2.0 m, and weight 49N
is used to support a load of mass m1 29.40 N
at a distance of 4.0m
and a second load of mass m2 49 N
at a distance of 6.0 m.
The boom is supported by a cable which is attached at 1.0m and acting at an angle of degrees 20 deg with respect to the boom. The tension here was 1346.70430N.. and i really have no idea deriving this answer..
