Question
A solid stepped bar is made of steel (E = 29 × 103 ksi, v = 0.32) and is fixed on both ends by rigid walls. The diameters of section A C and section CD are 0.25 in and 0.75 in respectively. When the 40 lb and 100 lb forces are applied at the point B and C respectively as shown, (a) sketch the free-body-diagrams for the entire bar and for each section needed for solving this statically indeterminate problem, (b) determine the reactions at A and D, i.e., Ra and Rp. dia. = 0.75 in D. dia. = 0.25 in A 40 lb 100 lb RA Rp = %3D 2 in + 2 in. 4 in
