A downward force y acts on a beam with a force of 10kN. This force acts 5 m from the left side of the beam. There is a vertical positive reaction at the left side of the beam, 15 m from the left side of the beam, and 30 m from the left side of the beam. The length of the beam is 30 m. Find all three positive vertical reactions in kN
