Q9). A test on a machine gave the following results: Load (KN) Effort (KN) 40 80 120 160 200 4.5 7.0 9.5 12.0 14.5 Given the table above complete the following tasks: a). Draw a graph of Effort (FE) versus Load (FL) to determine the law of the machine Note: FE = a.FL + b where FE is the effort applied FL is the load applied a is the slope of the graph b is the value of FE where the graph cuts the FE axis b). Using the law of the machine determine the effort required for a load of 175 KN ). For each of the test results in the table, calculate the efficiency and show that it tends towards a limiting value at large loads FL Machine Efficiency = n = %3D FEVR distance moved by effort = 12 %3D where VR = Velocity Ratio = distance moved by load 1 Demonstrate analytically that the limiting efficiency for the machine is n = aVR d).
