To solve this problem, we will apply the conditions for static equilibrium: the net force in both horizontal and vertical directions must be zero, and the net torque about any point must be zero. First, let's identify the forces and distances: Mass of beam (m_B) = 20 \, kg Length of beam (L) = 2.4 \, m Weight of beam (W_B) = m_B g = 20 \, kg × 9.8 \, m/s^2 = 196 \, N. This acts at the center of the beam, $L/2 = 1.2 \, \
