1.7-3 A polyethylene bar with a diameterd = 70 mm is placed inside a steel tube with an inner diameter d, = 70.2 mm (see figure). The polyethylene bar is then compressed by an axial force P. At what value of the force P will the space between the polyethylene bar and the steel tube be closed? For polyethylene, assume E = 1.4 GPa and v = 0.4. Steel tube d, d2 Polyethylene- bar

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.
