A test on a machine gave the following results: Q9)- Load (KN) Effort (KN) 0 40 80 200 160 120 2 4.5 14.5 7.0 12.0 9.5 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 FE a.FL+ b Note: FE is the effort applied where 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 Using the law of the machine determine the effort required for a load of 175 KN b). For each of the test results in the table, calculate the efficiency and show that it tends towards a limiting value at large loads c). FL Machine Efficiency n = FEVR distance moved by effort = 12 VR = Velocity Ratio where distance moved by load 1 Demonstrate analytically that the limiting efficiency for the machine is n= aVR d).
