Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 90 mm, 110 mm, and 150 mm, respectively. After stretching, band A has a length of 105 mm, while bands B and C each have a length of 210 mm. Determine the maximum normal strain in the bands.

A load of 17 kN is applied through a pin connection and a square bearing plate to the end of a beam that has a rectangular cross section. The base of the beam’s cross section is 96 mm and the height is 180 mm. The size of the bearing plate is 112 mm. Determine the bearing stress between the plate and the beam.

What type of boundary is shown on the figure below?

Before an automotive engine is started, its timing belt has a length of 45.00 in. and a temperature of 70°F. At the engine operating temperature of 220°F, it is determined that the belt has elongated to 45.04 in. What is the coefficient of thermal expansion of the belt?

A square that was initially a x a in size is deformed into the following shape. If a = 21 mm, b = 6.4 mm, and c = 20 mm, determine the magnitude of the shear strain at B. (Use the small-angle approximation sin γ ≈ tan γ ≈ γ.)

Three plates are connected with two bolts and transmit load P = 7.2 kN. Each plate is 4.0 mm thick, and each bolt has a diameter of 9.5 mm. Determine the average shear stress in the bolts.

A steel [E = 205 GPa, ν = 0.274] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 150-mm long and has a diameter of 5.0 mm. Determine the longitudinal strain in this portion of the rod when it supports a tensile load of 9.8 N.

A steel [E = 195 GPa, ν = 0.326] rod with a circular cross section is used as a weight hanger. The straight part of the rod is 170-mm long and has a diameter of 4.5 mm. Determine the longitudinal strain in this portion of the rod when it supports a tensile load of 12.0 N.

You have an unknown substance with a mass of 32 grams and a volume of 7 cm3. What is the density of the substance?

Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. If F1 = 35 kips, F2 = 14 kips, F3 = 21 kips, and F4 = 38 kips, determine the absolute value of the axial load in rod (2).
