For the co-planar force system shown below, determine by calculation, the resultant force in magnitude and direction. Give your answers to 2 decimal places. 230N 60N* 130 120N 70 RE 60N Find the magnitude. Use negative numbers where applicable, for example if the resultant points left or downwards. In x direction N In y direction N Total N Submit part 3 marks Unanswered b) Find the direction (120N is at 0 and counting counter-clockwise) in the range 0 A joint which is part of a loaded framework is shown below. The joint carries a vertically downward load of 12kN as shown and the horizontal force in OP is 10kN acting towards O. Give your answers to 2 decimal places. R 12 kN 80 60 10 kN P a) Find the force in member OR. KN b) Find the force in member OQ. KN Submit part 3 marks Unanswered Submit part 3 marks Unanswered A uniform beam of length 7m is shown below and is simply supported at its left hand end (A) and at a point (B) 5m from A. It carries a vertically downward load of 12kN as shown below and is to carry a further vertically downward load of 36kN in such a position that the upward reactions at each support are equal. A 12 kN 1 2 3 G B 6 m IN 7 Ignore the weight of the beam and determine the position of the 36kN load to fulfil the given conditions. Measure from A. m Calculate the pressure exterted at the base of a 4.2m high column of glycerine with a density of 1263 kg. m. Use 9.81 for g. Give your answer in bar to 2 decimal places.
