1. True or False. Write TRUE if the statement is correct and FALSE if the statement is incorrect. (5 pts. each) 1. Stress is pressure exerted on a material object; it may have a unit of kN. 2. Strain is force per unit area, and has no unit. 3. Stress is considered normal when the force is parallel to the cross section. 4. Stress is considered shear when the force is perpendicular to the cross section. 5. Normal stress is also called tangential stress. II. Problem Solving. Write your complete solutions and indicate proper units. 1. Determine the normal stress at bar AC. Use diameter of bar AC = 215 mm. (25 pts) 500 N 2 m 451 2 m 2.
