Quiz-b
Show a trend using graphical solution with added friction mu = 0.25, hanger mass values = 4 kg & 8 kg
Incline 40 degrees, incline-object = 2 kg, sliding friction coefficient mu = 0.25
Use 9.8 m/s/s for g
Transcribed Image Text:Quiz-a
Show a trend using graphical solution with added sliding friction coefficient values mu = 0.25 & 0.4
Incline 40 degrees, incline-object = 2 kg, hanger mass = 4 kg
Use 9.8 m/s/s for g
Describehow mu increased, acceleration down, but tension intemal force up
Plot tension on y-axis, acceleration on x-axis for the 2 kg mass with mu =0.25 using the 2 kg equation of
(T, a). Repeat for the 4 kg using the 4 kg equation of (T, a) on the same graph, the intersection is the
graphical solution. Repeat for the 2 kg with mu=0.4 using the 2 kg equation of(T, a) on the same graph,
the intersection is the graphical solution.
Writing intensive: explain the graph as a trend justification, the shift of the intersection points to other
values.
