A solid round bar carries an axial tensile load P. Find the normal stress σ in the bar.
Axial stress & strain worksheet with answers
A steel rod (diameter 30 mm, E = 200 GPa) sits inside a tube made of bronze (outer diameter 100 mm, inner diameter 50 mm, E = 110 GPa). Both are 800 mm long and are compressed together between rigid plates by 100 kN. Find the compressive stress σr in the rod.
A steel rod (diameter 30 mm, E = 200 GPa) sits inside a tube made of bronze (outer diameter 100 mm, inner diameter 60 mm, E = 110 GPa). Both are 600 mm long and are compressed together between rigid plates by 250 kN. Find the shortening δ.
Find the elongation δ of the steel bar under the axial load.
The stepped bar is fixed at the wall and loaded at its free end. Find the total elongation δ.
A steel segment (diameter 40 mm, length 500 mm, E = 200 GPa) and a segment made of bronze (diameter 40 mm, length 300 mm, E = 110 GPa) are joined end to end and fixed between two rigid walls. An axial load of 40 kN acts at the joint, towards segment 2. Find the magnitude of the stress σ2 in segment 2.
