02:46 Problem 1

• Critical Section is a section that has maximum Bending Moment because it causes more stresses and is thus more critical
• When calculating Loading Conditions at a section, make sure to label axes on the structure to label loads appropriately
• Bending moment/Normal force ⇒ Normal stress
• Shear force/Torque ⇒ Shear Stress
