A steel rod with a circular cross section is used as a weight hanger. The straight part of the rod is 135-mm long and has a diameter of 4.1 mm. Determine the magnitude of the lateral strain in this portion of the rod when it supports a tensile load of 11.0 N.

Before an automotive engine is started, its timing belt has a length of 39.00 in. and a temperature of 60°F. At the engine operating temperature of 210°F, it is determined that the belt has elongated to 39.04 in. What is the coefficient of thermal expansion of the belt?

A wooden cylinder of diameter D and a concrete cube of size D sit on the floor. Assuming they weigh the same amount, which produces the smaller bearing stress on the floor?

A steel rod with a circular cross section is used as a weight hanger. The straight part of the rod is 170-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 12.0 N.

Two plates are connected with two bolts and transmit load P = 7.6 kN. Each plate is 4.0 mm thick, and each bolt has a diameter of 10.2 mm. Determine the average shear stress in the bolts.

Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. If F1 = 30 kips, F2 = 10 kips, F3 = 22 kips, and F4 = 36 kips, determine the absolute value of the axial load in rod (2).

Most exercise routines combine anaerobic and aerobic exercise for maximum benefit. Consider homeostasis and the ability to complete physical activity in different environments. Consider an exercise routine and describe how each organ system contributes to being able to complete this routine. I am looking for a key term or two for each organ system – not a lengthy explanation.  You should list functions for eight organ systems. Rely on information provided in Chapter 1 of your textbook. 

Which type of specimen is most likely to require oil immersion and measurement with a calibrated micrometer?

Alejandra, a behavior analyst is analyzing her data on elopement and evaluating whether her intervention was successful. Alejandra determines she has sufficient data points, with a high, stable trend in baseline and a low, stable trend in the intervention.  What should Alejandra have already done as part of conducting a visual analysis prior to determining if she has sufficient data?

Rigid pipe (2) is supported by a pin connection at C and tie rod (1). The structure supports a load P = 10 kN at pin B. Assume x1 = 3.3 m, x2 = 2.2 m, and y1 = 3.7 m. Determine the force in tie rod (1).
