The lfll problemsfquesliooe in problem 3 are worth 1 point each. and there is no partial credit for each of these lflprohlenietqueations. Partial Credit wiil be awarded in Problems 1 and 2, but only if the work is neat. orderly. and adequately explained. - Check whether you have all ti pages in your test booklet. :- Budget your time. 0 You may superimpose free body diagrams directl}r upon given sketches wherever it can he done clearly and unambiguously. 1 P1} Draw the shear flirue and bending 111omcm diagrams for the beam sham-n beiow.
