Question

A shaft turning at a uniform speed carries two uniform discs A and B of masses 10kg and 8kg respectively. The centres of the mass of the discs are each 2.5mm from the axis of rotation. The radii to the centres of mass are at right angles. The shaft is carried in bearings C and D between A and B such that AC = 0.3m, AD = 0.9m and AB = 1.2m.

It is required to make dynamic loading on the bearings equal and a minimum for any given shaft speed by adding a mass at a radius 25mm in a plane E.

USING THE METHOD OF DRAWING m*r and m*r*l diagram

Determine:

The magnitude of the mass in plane E and its angular position relative to the mass in plane A
The distance of the plane E from plane A
The dynamic loading on each bearing when the mass in plane E has been attached and the shaft rotates at 200 rev/min. For the bearing loads in the opposite direction determine all the unknown values. For the bearing loads in the same direction, show the diagrams and equations only to use for a possible solution.

A shaft turning at a uniform speed carries two uniform discs A and B of masses 10kg and 8kg
respectively. The centres of the mass of the discs are each 2.5mm from the axis of rotation. The radii to
the centres of mass are at right angles. The shaft is carried in bearings Cand D between A and B such
that AC = 0.3m, AD = 0.9m and AB = 1.2m.
It is required to make dynamic loading on the bearings equal and a minimum for any given shaft speed
by adding a mass at a radius 25mm in a plane E.
Determine:
1. The magnitude of the mass in plane E and its angular position relative to the mass in plane A
2. The distance of the plane E from plane A
3. The dynamic loading on each bearing when the mass in plane E has been attached and the shaft
rotates at 200 rev/min. For the bearing loads in the opposite direction determine all the unknown
values. For the bearing loads in the same direction, show the diagrams and equations only to use
for a possible solution.
