See right as a square-shaped closed cross-section of a thin-walled beam. shear loads of the same magnitude are applied both in the x and y directions (sx=sy=s0) at the shear center.

a) solve for the shear flows along the walls.
b) provide a sketch of the shear flows along the walls, in the similar manner as in the slide 35 of ln4.

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.
