please help me with this statics problem, thank you

1. Structural Questions: Fig. 1 depicts a continuous beam supported at locations 1 and 2 by pin joints. A static load P is applied at location 3. Using the sign convention indicated and ignoring the weight of the beam write the expressions for the reaction loads at locations 1 and 2. +X R2Y Figure Complete the free body diagram below, for a cross section cut to Fig. 1 at distance d which is slightly less than a: (Moments and loads need to be expressed in terms of P, a, b, d and 6.) At what location (1, 2, 3 or somewhere in between) will the beam experience its maximum tensile stress? If the beam has a square cross section of w x w (m), write the expression for the maximum tensile stress in terms of P, a, b, w and 0. (Recall that: I for a rectangle is r a rectangle is base height 12 OMAX
