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 velocitv = 0 m/s Time to descend = A secs 2. ( Distance travelled = 0.25m You have been asked to use this information to determine with 4 s.f. accuracy: Drum Cable a) The final linear velocity of the load b) The linear acceleration of the load 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 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.

Drum
Cable
a) The final linear velocity of the load
b) The linear acceleration of the load
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
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.
