When a stationary mass of gas was
compressed without friction at
constant pressure its initial state of
0.8 m3 and 0.105 MPa was found to
change to final state of 0.40 m3 and
0.105 MPa. There was a transfer of 85
kJ of heat from the gas during the
process.How much did the internal
energy of the gas change ? *

The pipe assembly of the figure is supported by a fixed support at point A. A couple-moment
and a force are applied at points B and C, respectively. In Cartesian coordinates, the applied
couple-moment is MB = -150 k N-m, and the applied force is Fc = + 200ĵ Newtons. You
may neglect the weight of the pipe assembly.
1. Draw a FBD which is suitable for solution of this problem, when seeking the unknown
force and moment reactions at the fixed support, Point A. You may use the existing
drawing given below.
Your FBD must clearly/correctly show the force and moment reaction vectors. Use double
arrowheads to distinguish moment vectors from force vectors.
2. Calculate F°MA, which is the moment generated at A due to the force applied at Point C.
3. Write the equations of equilibrium and solve to find the reactions at Point A. Specifically,
find the force-reaction vector, A and the moment-reaction vector, *MA-
