Consider a circular cross-section which experiences an internal torsional load T=17 Nm, an internal bending moment M_y=24 Nm, and an internal shear force V= 10 kN. All loads act in the directions shown in the figure below. The cross-section has a diameter, d=69 mm.

Given these internal loads in the cross-section, calculate the stresses at point B.
Determine the normal stress, alphaB, and shear stress tauB, at point B in MPa

Ans: SigmaB = 0.7441, TauB = -28.7895
I need help getting to the answer.

The characteristic roots of a dynamic system are: 1.7920 1.8160 i, -1.7920 1.8160 i, -0.4160 what is the order of this system? what are the settling time and damping ratio of the system?

An insulated tank truck containing 50,000 pounds of double-distilled, deionized water at 30 °c is pumped into a closed, refrigerated storage tank maintained at 5 °c in a facility located on top of mount mitchell, north carolina (elevation 6,684 feet & average july temperature of 84 °f). a)-determine the volume of the storage tank required to hold the purified water. b)- determine the initial and final pressure differences that must be overcome by a liquid pump assuming the storage tank initially contains air at 5 °c. assume the air is slowly bled out of the storage tank during the water transfer c.) during a routine operation today, the tank is slightly ruptured by a stainless steel pipe and a water acrosol of droplets begins to spray out of the storage tank. state all assumptions and determine the internal pressure within the water droplets produced
