2. The shaft is supported
at

A
by a
journal

bearing that exerts only vertical reaction

on the

S
haft

and at B by
a
thrust bearing that exerts both horizontal and vertical

reactions on the
shaft, draw

the
bending moment

diagram for the shaft and then

from this diagram sketch the
deflection or elastic curve for the shaft
’s

centre line.

Determine: The
deflection
at x

= x
2

= 100mm
and assume E= 200 GPa
and

diameter of the shaft is 20 mm,
as shown in the figure
