Question

Compute the reaction developed at support in the cantilever beam shown in Fig.

Answer 1

Let the vertical reaction be VA and moment be MA. There is no horizontal component of reactions, since no load is having horizontal component 

ΣV = 0, gives 

V_A – 20 × 2 – 15 × 10 = 0

V_A = 65 kN. 

ΣM = 0, gives 

M_A – 20 × 2 × 1 – 15 × 3 – 30 – 10 × 5 = 0 

M_A = 165 kN-m
