Here are the questions of the first exam: Exam 1 (2)-1.pdf

Which of the following is an example of a mathematical statement? (A) Chocolate milkshakes are delicious. (B) My boyfriend is taller than I am.  (C) There is too much traffic on Highway 280. (D) 23 is the coolest basketball jersey number.   

A steel rod with a circular cross section is used as a weight hanger. The straight part of the rod is 145 mm long. Determine the minimum diameter D required if this portion of the rod must hold a tensile load of 11.0 N without stretching more than 0.00455 mm.

A load of P = 375 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 1.15 in. If the normal stress in bar (1) is limited to 10 ksi, determine the factor of safety for bar (1). Let a = 34 in., b = 12 in., and c = 9 in.

A short column is composed of two steel segments, each with a length of 5.1 in. Segment (1) is hollow with an outside diameter of 1.20 in. and a wall thickness of 0.10 in. Segment (2) is hollow with an outside diameter of 1.40 in. and a wall thickness of 0.10 in. How much shorter does the column become after a load of P = 690 lb is applied?

A load of P = 265 lb is applied to beam ABC. Determine the normal force in bar (1). Let a = 37 in., b = 12 in., and c = 8 in.

Two pieces of high-density polyethylene tubing are fitted together and firmly clamped at their ends. A load of 174 N is applied to the fitting. Tube (1) is 160 mm long, and tube (2) is 110 mm long. Both tubes have an outsider diameter of 21.0 mm and an inside diameter of 15.6 mm. Determine the load carried by tube (2).

Two pieces of high-density polyethylene tubing are fitted together and firmly clamped at their ends. A load of 100 N is applied to the fitting. Tube (1) is 155 mm long, and tube (2) is 90 mm long. Both tubes have an outsider diameter of 23.0 mm and an inside diameter of 18.0 mm. Determine the load carried by tube (2).

A load of P = 390 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 1.01 in. If the normal stress in bar (1) is limited to 10 ksi, determine the factor of safety for bar (1). Let a = 32 in., b = 16 in., and c = 8 in.
