( 50 points) The beam below has a diameter of 20 mm . It also has allowable stresses of
\sigma _(allow )=30MPa
and
\tau _(allow )=10Mpa
. a. (3 points) Draw and label the support reactions on the beam. b. (10 points) Solve for all support reactions.c. (15 points) Find the internal loadings at point C on the beamd. (9 points) What is the average shear stress at point C e. (9 points) What is the average normal stress at point C ?f. (4 points) Is the beam adequate? Why or why not?
