Some applications of mathematics to bicycle gearing, speedometers, and bicycle braking are discussed. A method of calculating bicycle speed is developed. (MP)

Provides directions for constructing graphical alignment charts to solve a variety of mathematical physics problems. (MLH)

This experiment designed for beginning physics students, is related to postal regulations restricting the size of envelopes. A graph is constructed that allows for testing the mailability of envelopes. (MP)

Develops a graphical method for studying the parallel susceptibility of an antiferromagnetic material. (SL)

Describes a computer program that computes field lines and equipotential surfaces for a wide range of field configurations. Presents the mathematical technique and details of the program, the input data, and different modes of graphical representation. (MLH)

Introduces an activity that focuses on Hooke's law to implement and furnish applications of linear equations and graphing in a physical situation. (KHR)

Argues that the only reason to ask students to plot graphs manually should be to have them learn the skill of plotting graphs manually. For data-analysis purposes, the use of computer-generated graphs has several advantages and few disadvantages over manual plotting. (Author/WRM)

Presents a lesson involving the measurement of wood beams and the prediction and testing of their stress limits. Provides an example of a problem with multiple solutions, each with different consequences. (KHR)

Described is a procedure for studying the trajectories of projectiles using ball bearings and aluminum foil. Trajectories were measured with and without the effects of air resistance. Multiflash photography was used to determine the flight paths of all objects. (KR)

Attempts to determine, using estimations and current power-law relationships, whether a newspaper report concerning the statement that a single 40,000-kg truck does as much damage to the highway as 9,600 cars is true. Provides a mathematical and graphical possible solution. (MVL)

Presented is a science activity which explains the discrepancies found between summer and winter solstice sunrise and sunset times. Used is a mathematical equation which takes into account the earth's changing speed and the tilt of the earth. (KR)
