    An overhanging beam PQR is subjected to uniformly distributed load 20 ...

    Taking 0A
    ΣM= 0,
    RQ × 2−(20 × 3×1.5) = 0
    RQ = 45 kN
    Taking ΣFy = 0,
    RP + RQ= 60
    RP + 45= 60
    RP= 15 kN


    25x = 30−15x
    x = 0.75 m
    For (BM)P =  0

    For (BM)R =  0




    = 250 MPa
