A hollow, circular, cast-iron pipe (E_c
=12,000 ksi) supports a brass rod (E_b
= 14,000 ksi)
and weight W = 2 kips, as shown. The outside diameter
of the pipe is d_c
= 6 in.
(a) If the allowable compressive stress in the pipe
is 5000 psi and the allowable shortening of the
pipe is 0.02 in., what is the minimum required
wall thickness t_c,min? (Include the weights of the
rod and steel cap in your calculations.)
(b) What is the elongation of the brass rod δ_r
due to
both load W and its own weight?
(c) What is the minimum required clearance h?
