The asymmetric roof truss is of the type used when a near normal angle of incidence of sunlight onto
the south-facing surface ABC is desirable for solar energy purposes. The five vertical loads represent the
effect of the weights of the truss and supported roofing materials. The 400-N load represents the effect
of wind pressure. Determine the equivalent force–couple system at A. Also, compute the x-intercept of
the line of action of the system resultant treated as a single force R.

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
