the objective of this lab was to figure out what the efficiency of the winch machine would be. the machine had to lift 100g of weight.
what we needwork (Joules)
Power out
Power in
Efficiency

Formula used.Force * Distance
Work/Time
Amps*Volts
(Power out/Power in)*100
|
calculation solved0.98n*18cm=17.64J
17.64J/625=0.285V
0.1A*9.04V=0.904 P in
(0.285 P out/0.904 P in) * 100 = 31.53%

results
The Efficiency of out machine was 31.53%
Final thoughts: what could have made it more efficient.
We could of change the gear to be smaller. Doing that would make the gear go more rotation which would make it faster.
We could have also lubricated the gears. This would have taken away some fo the frictions.
