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.

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.
