Question

What force and moment is transmitted to the supporting wall at A? (Fig).

Answer 1

∑H = 0

∑V = – 5 × 1.5 + 15 + 1/2 × 1.5 × 10

= 15 kN 

MA = 1.5 × 5 × 0.75 – 15 × 2 – 1/2 × 1.5 × 10 × (2.5 – 1.0)

= – 35.625 kNm

A force of 15 KN (vertical) is transmitted to the wall along with an anticlockwise moment of 35.625 kNm.
