Mechanical and structural analysis miscellaneous
  1. The sketch shows a column with a pin at the base and rollers at the top. It is subjected to an axial force P and a moment M at mid-height. The reaction(s) at R is/are
    1. a vertical force equal to P
    2. a vertical force equal to P/2
    3. a vertical force equal to P and a horizontal force equal to M/h
    4. a vertical force equal to P/2 and a horizontal force equal to M/h
Correct Option: C

P will cause direct vertical reaction at R. Take moment about Q.
RH .h - M = 0
∴ RH = M/h
