Answer to Problem 1RQ
The evaporating temperature of liquid nitrogen and
Explanation of Solution
Evaporation is a process in which a liquid turns into gas. The temperature at which evaporation starts is called evaporating temperature. Evaporation can occur at any temperature and pressure greater than zero Kelvin or absolute zero temperature. The temperature at which evaporation starts is called the evaporating temperature of that liquid. Evaporation is different phenomenon than boiling. Boiling starts at a particular temperature while the evaporation can takes place at any temperature greater than the absolute zero temperature.
Liquid nitrogen is colorless which starts evaporating at
Carbon dioxide consists of a carbon atom and two oxygen atoms. Carbon atom is covalently bonded with both of the oxygen atoms. They are linked with two double bonds and can be written as
Conclusion:
The evaporating point for liquid nitrogen is

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
