but need to check that the angle between the edges of the bracket is precisely the same angle that the beams are required to be, compared to the engineering drawing. X- O 400 mm B 250 mm 300 mm 50 mm (c) Determine the displacement vector, s = =PQ cond 101 (a) Write the position vectors along the top edge (OA) and right edge (OB) of the bracket. (b) Determine the angle (u) between the edges of the sheet-metal bracket (in the plane AOB). This whole structure is supporting the aircraft engine. In flight, a force of F = 5i +3j - 2k newton's is applied to the engine, which moves it from position P = (1, 1, 1) to position Q = (5,-1,2) (in metres). (d) Determine the work done by the force F, in moving the object from P to Q. (Work done = Force x Displacement)
