Stress Problem - Horizontal Load L h F 9. A metal bar is shown above with a width of "b" into the page and the modulus of Elasticity "E." L = 250 cm, h=2.5 cm, b=5 cm, E = 70 GPa, F = 200 N a. What is the maximum principal stress in the bar? Show equation and numerical value. (2 pt) b. The direction of force is reversed so that it is in the negative x direction, as shown below. What additional failure criteria should be considered to determine if the bar could withstand the loading? (2 pt) 10. Beam Problem - Vertical Force (3 pt) A metal bar is shown below. L IF F Draw the letter "C" at the point of maximum Compressive stress. b. Draw the letter "T" at the point of maximum Tensile stress. Draw the letter "B" at the point along the length L where it is most likely to Break.
