With reference to the attached example. 

Apply dimensinal analysis to show that all values/units used are homogeneous.

Data has been gathered from a lifting system used to transport engine parts. The system consists
of a drum and cable. The following data was obtained when the drum lowers the load (assume
constant acceleration).
Drum diameter = 0.8m
Mass of load = 3kg
Initial velocity = 0 m/s
Time to descend = 0.5 secs
Distance travelled = 0.25m
You have been asked to use this information to determine:
a) The final linear velocity of the load
b) The linear acceleration of the load
c) The final angular velocity of the drum
d) The angular acceleration of the drum
e) The tension force in the cable
f) The torque applied to the drum
Drum
Cable
Load
In determining the above quantities, you should clearly state the formulae used and apply
dimensional analysis techniques to show that all values/units used are homogeneous.
From the formulae used (above) you should apply dimensional analysis techniques to develop two
equations for power (in terms of linear velocity and angular velocity).
