Question
A circular bar ACB of a diameter d having
a cylindrical hole of length x and diameter d/2 from
A to C is held between rigid supports at A and B.
A load P acts at L/2 from ends A and B. Assume E
is constant.
(a) Obtain formulas for the reactions RA and RB at
supports A and B, respectively, due to the load
P (see figure part a).
(b) Obtain a formula for the displacement d at the
point of load application (see figure part a).
(c) For what value of x is RB = (6/5)RA? (See figure
part a.)
(d) Repeat part (a) if the bar is now rotated to
a vertical position, load P is removed, and
the bar is hanging under its own weight
(assume mass density =p ). (See figure part b.)
Assume that x = L/2.
