3 Determine the reactions at the supports A and B. Use discontinuity functions. EI is constant. (Figure 1) Figure A -12- -14/20 < 1 of 1 B is directed upward and negative value if the force is directed downward. Ay = Submit Part B MA= IVE | 1 Submit Request Answer V Determine the moment of reaction at A. Express your answer in terms of some or all of the variables L, E, I, and P. Enter positive value if the moment is directed counterclockwise and negative value if the moment is directed clockwise. vec Request Answer vec ? SESTA 11111 ? Review
