A beam 10m long has a uniformly distributed load of 14kN/m over its full length. It has. Appoint load of 125kN, 3m from the left-hand end. It is supported at the left-hand end and at 8.5m from the left-hand end. a) Indicate the value of the support reactions (Ra and Rb) b) Calculate the reaction forces Ra and Rc below: 10 kN/m 4mm 20 kN B C A D 4m 2m c) Determine the pressure at the bottom of a swimming pool 2.5 meters deep. d) A hot air balloon rises off the ground because the density of air in the balloon is less than the density of the atmosphere. Suppose that a spherical balloon has a diameter of 5 meters and that the density of air is constant at 1.225kg/m³. How much weight can the balloon lift and remain at a constant altitude?
