Concept explainers

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.

Question

A 75-cm-long cylindrical rod of cross-sectional area A, = 0.5 cm² is placed inside a tube of
the same length and of cross-sectional area A, = 0.65 cm2. The ends of the rod and tube are
attached to a rigid support on one side, and to a rigid plate on the other. The rod is pure
elastic, but the tube is elastoplastic. The rod has modulus of elasticity E, = 250 GPa. The
tube has modulus of elasticity E, = 120 GPa and yield strength (ot)y = 320 MPa. If the
load P applied to the rod-tube assembly is increased from zero to 70 kN and decreased back
to zero, determine the permanent set (Sp) of the rod-tube assembly after the load P has been
completely removed.

can you help me answer this question using the figure provided? thank you.
A disk of SBR elastomer 3.0 cm in diameter 0.5 cmthick is used as a cushioning surface between two steel rods ofthe same diameter, as shown below (not to scale). a. If the rods are brought together with an axial force of 100 N such that the SBR is compressed elastically between them, what is the thickness of the SBR under load? b. Under the same conditions as part (a), what is the greatest possible diameter of the SBR under load? c. If the SBR is bonded to the rods, how far can one rod be rotated with respect to the other before the SBR/rod interface fractures? Assume that the rods are essentially rigid and the distance between them remains constant. Please answer in degrees of rotation.

Rigid bar ABCD is loaded and supported. Bars (1) and (2) are unstressed before the load P is applied. Bar (1) is made of bronze [E= 100 GPa] and has a cross-sectional area of 400 mm2. Bar (2) is made of aluminum [E= 70 GPa] and has a cross-sectional area of 600 mm2. After the load P is applied, the force in bar (1) is found to be 60 kN (in compression). Determine: (a) the stresses in bars (1) and (2).(b) the vertical deflection of point A.(c) the load P.
