An L-shaped rigid member is fixed at the midpoint of a simply-supported beam, as shown in figure (i). The member is subjected to a vertically downward force P at its free end. In an equivalent system, the member along with the applied load is replaced with a force Q = P and a moment M (see figure (ii)). Which of the following statements is correct? (Neglect the mass of the beam and of the rigid member)
- A. M = P a
- B. M = P b
- C. M = P (a + b)
- D. M = 0
Answer: A. M = P a
