A. Which type of fat is the least healthy?  B. Are unhealthy fats liquid or solid at room temperature? 

Rigid pipe (2) is supported by a pin connection at C and tie rod (1). The structure supports a load P = 16 kN at pin B. Assume x1 = 3.9 m, x2 = 2.3 m, and y1 = 4.5 m. Determine the force in tie rod (1).

What event began the Thirty Years’ War? 

Two plates are connected with two bolts and transmit load P = 6.4 kN. Each plate is 5.3 mm thick, and each bolt has a diameter of 9.2 mm. Determine the average shear stress in the bolts.

A steel rod with a circular cross section is used as a weight hanger. The straight part of the rod is 155-mm long and has a diameter of 4.4 mm. Determine the longitudinal strain in this portion of the rod when it supports a tensile load of 7.8 N.

Manatees prefer human-modified environments over natural ones.

Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. If F1 = 33 kips, F2 = 13 kips, F3 = 21 kips, and F4 = 39 kips, determine the absolute value of the axial load in rod (2).

Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 90 mm, 115 mm, and 150 mm, respectively. After stretching, band A has a length of 100 mm, while bands B and C each have a length of 200 mm. Determine the maximum normal strain in the bands.

A short column is loaded in compression. Segment (1) has a solid cross section with a diameter of 1.00 in. Segment (2) is hollow with an outside diameter of 1.26 in. and a wall thickness of 0.13 in. If segment (2) has a normal stress of 10 ksi, determine the normal stress in segment (1).

Rigid pipe (2) is supported by a pin connection at C and tie rod (1). The structure supports a load P = 16 kN at pin B. Assume x1 = 3.0 m, x2 = 2.5 m, and y1 = 4.5 m. Determine the force in tie rod (1).
