The beam ABC has a mass of 79.0 kg and is supported by
the rope BDC that runs through the frictionless pulley at D
. The winch at C has a mass of 36.5 kg. The tension in the
rope acts on the beam at points B and C and counteracts
the moments due to the beam's weight (acting vertically at
the midpoint of its length) and the weight of the winch
(acting vertically at point C) such that the resultant moment
about point A is equal to zero. Assume that rope segment
CD is vertical and note that rope segment BD is NOT
necessarily perpendicular to the beam.
a.) Compute the tension in the rope.
b.) Model the two forces the rope exerts on the beam as a
single equivalent force and couple moment acting at point B.
Enter your answer in Cartesian components.
c.) Model the two forces the rope exerts on the beam as a
single equivalent force (no couple) and determine the
distance from A to the point along the beam where the
equivalent force acts (measured parallel to the beam from A
). Enter your answer…

Three distributed loads act on a beam as shown. The load
between A and B increases linearly from 0 to a maximum
intensity of w₁ = 12.8 lb/ft at point B. The load then varies
linearly with a different slope to an intensity of w₂ = 17.1
lb/ft at C. The load intensity in section CD of the beam is
constant at w3 10.2 lb/ft. For each load region, determine
the resultant force and the location of its line of action
(distance to the right of A for all cases).
