TAM 210/211 BL1, Fall 2004 Sample Exam 3 You must show all your work to receive full credit 1. First, use eq conditions for the object as a whole: 0 0 = = x x C F ; Q C D F y y y = + = 0 () ( ) 3 / 2 3 / 0 3 2 0 L D L C C L L Q L y y y D = = = × + + × = j i j i M Then, solve for equilibrium at pin C: 2 3 / 0 BF y F Q F = = 3 / 2 0 Q F F F BF BC x = = = , compression Now, we can use the method of sections to solve for F DE . For the section shown: () () ( ) 0 3 / 2 0 = × + × = i j j j i M DE A F L Q L L 3 / 2 Q F DE = , tension 2. First, use eq. conditions for the object as a whole to find reactions at the supports expressing the distributed force as an equipollent concentrated force: 0 0 = = x x A F ; N B A F y y y 3 0 = + = () N A N B B m N m y y y A 2 1 0 6 3 2 0 = = = × + × = j i j i M Then, solve the eq. conditions for a portion of the bar from x = 0 to x < 3m expressing the distributed force as an equipollent concentrated force:
