Simple Machine – Pulley Block

Title: Simple automobile engine block block Date: 21/04/2010 Theory: The objective of the look into is to calculate the f add balance and mechanical utility for different pulley arrangements. Formulae associated with the try be: Mechanical improvement = M.A. upper Ratio = V.R. = 2) Results of examine: Results: The velocity ratio of the pulley system is equal to the outlet of restless ropes between the sheaves. whence: Type of pulley arrangementVelocity Ratio realize 11 Figure 22 Figure 34 Fig. 1 Fig. 2 Fig. 3 Pulley arrangement shown in Fig.1 Load [kg]% actus reus for appoint [%]Load [N]Effort [N]% wrongdoing for effort [%]M.A.% computer misplay for M.A. [%]V.R.% Efficiency% illusion for % energy [%] 0.50050.0204.915.250.1910.930.211193.00.211 0.60120.0175.906.250.1600.940.177194.00.177 0.70230.0146.907.250.1380.950.152195.00.152 0.80020.0137.858.250.1210.950.134195.00.134 0.90150.0118.849.250.1080.960.119196.00.119 1.00000.0109.81MAXED OUTN/AN/AN/A1N/AN/A Pulley arrangement shown in Fig.2 Load [kg]% flaw for consign [%]Load [N]Effort [N]% computer error for effort [%]M.A.%error for M.A. [%]V.R.% Efficiency%error for % cogency [%] 0.50040.0204.
