Question

FOR FIG REFER ATTACHED FILE
The shaft is massless. A thin attached triangular mass ‘m’ is mounted on the shaft. Rotational speed of the shaft is ω. Neglect weight effect of attached mass. Bearings are at A and B.
Take Z- axis along the shaft axis. X- axis is vertically downward. Y – axis is horizontal. Take origin at mid-point on the shaft (As shown in fig).

QUESTIONS:

Rotate the shaft by 90 degrees and using the moment equation about ‘A’ and force equation to obtain the bearing reactions at
‘A’ and ‘B’.

Equilateral A of side b
at C.
O is the origin.
