A short column is loaded in compression. Segment (1) has a solid cross section with a diameter of 1.10 in. Segment (2) is hollow with an outside diameter of 1.50 in. and a wall thickness of 0.20 in. If segment (2) has a normal stress of 17 ksi, determine the normal stress in segment (1).

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.)

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?

Rigid pipe (2) is supported by a pin connection at C and tie rod (1). The structure supports a load P = 20 kN at pin B. Assume x1 = 3.6 m, x2 = 1.1 m, and y1 = 4.4 m. Determine the force in tie rod (1).

Two plates are connected with four bolts and transmit load P = 5.9 kN. Each plate is 6.0 mm thick, and each bolt has a diameter of 10.8 mm. Determine the average shear stress in the bolts.

[FinB] Carol is a behavior analyst working in a group home for adolescents with intellectual delays and behavior problems.  JR is a resident in the group home and often engages in skin picking that causes chronic tissue damage.  During JR’s summer break from school, Carol implements an intervention in the group home, which reduces JR’s skin picking to a near- zero rate. However, Carol hears that JR continues to pick his skin during visits to his family home.  Carol meets with JR’s parents and asks them to begin taking baseline data on the skin picking. During this period, Carol trains the parents on the intervention, which eventually reduces skin picking in the family home.  When JR’s school resumes in the fall, Carol meets with JR’s teacher to set up baseline data collection on skin picking in the classroom to see if the intervention is also necessary at the school. Which experimental design would be most appropriate for Carol to use?

A load of 13 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 76 mm and the height is 170 mm. The size of the bearing plate is 86 mm. Determine the bearing stress between the plate and the beam.

Before an automotive engine is started, its timing belt has a length of 38.00 in. and a temperature of 60°F. At the engine operating temperature of 220°F, it is determined that the belt has elongated to 38.04 in. What is the coefficient of thermal expansion of the belt?

Three plates are connected with two bolts and transmit load P = 4.8 kN. Each plate is 5.8 mm thick, and each bolt has a diameter of 10.4 mm. Determine the average shear stress in the bolts.

A short column is loaded in compression. Segment (1) has a solid cross section with a diameter of 1.10 in. Segment (2) is hollow with an outside diameter of 1.44 in. and a wall thickness of 0.17 in. If segment (2) has a normal stress of 14 ksi, determine the normal stress in segment (1).
