Pulley Lab Report Data *to get resistance force: multiply mass kg x 9.8m/s2 *effort force is the reading on your scale in N *resistance distance is how much the weight moves *effort distance is how much the scale moves Mass kg Resistance force Effort force Build Figure A-fixed pulley Resistance Effort distance distance 0.5 kg 1.0 kq Mass kg 0.5 kg 1.0 kq Resistance force Build FIGURE E -block and tackle Effort force Resistance Effort distance distance Mass 0.5 kg 1.0 kg Mass 0.5 kg 1.0 kg Table 3 *work input = effort force x effort distance *work output = resistance force x resistance distance FIXED PULLEY BLOCK & TACKLE Work Input (J) Work Output (J) Mass Work Input (J) Work Output (J) 0.5 kg 1.0 kg Table 4 Efficiency = work output/work input x 100 FIXED PULLEY Efficiency Efficiency Mass 0.5 kg BLOCK & TACKLE Efficiency Efficiecny 1.0 kg Analysis 1.The effort distance is very much greater than the resistance distance in which machine? 2.The effort force is very much less than the resistance force in which machine? 3.In which machine is the work output greater than the work input? 4.Explain how using a single fixed pulley to raise a flag makes the task easier: 5.Explain how using a single fixed pulley to raise a flag makes the task easier: 6.Compre the efficiencies of the single fixed pulley and the block and tackle. Why would you expect the block and tackle to be less efficient than the single fixed pulley?
