Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. If F1 = 35 kips, F2 = 16 kips, F3 = 24 kips, and F4 = 40 kips, determine the absolute value of the axial load in rod (2).

Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. If F1 = 31 kips, F2 = 14 kips, F3 = 28 kips, and F4 = 37 kips, determine the absolute value of the axial load in rod (2).

Which of the following structures is primarily responsible for stabilizing the lateral side of the knee?

A load of 19 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 90 mm and the height is 190 mm. The size of the bearing plate is 104 mm. Determine the bearing stress between the plate and the beam.

A load of 12 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 68 mm and the height is 200 mm. The size of the bearing plate is 88 mm. Determine the bearing stress between the plate and the beam.

Relate an animal’s flight zone distance to it’s familiarity with being handled by people. 

What should you do if you spill a bacterial culture on the lab bench?

A square that was initially a x a in size is deformed into the following shape. If a = 24 mm, b = 6.9 mm, and c = 23 mm, determine the magnitude of the shear strain at C. (Use the small-angle approximation sin γ ≈ tan γ ≈ γ.)

Before an automotive engine is started, its timing belt has a length of 41.00 in. and a temperature of 60°F. At the engine operating temperature of 210°F, it is determined that the belt has elongated to 41.04 in. What is the coefficient of thermal expansion of the belt?

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.
