This report and any related files are made available to the online through the Lester F. Larsen Tractor Test and Power Museum as resources allow. Established in 1998, this museum is located on the University of Nebraska-Lincoln East Campus. It is and appropriately housed within the walls of the historic 1920 Nebraska Tractor Test Laboratory, where the first tractor test was started on March 31st, 1920. Because the pioneer tests became worldwide standards, this location was designated as a Historic Landmark of Agricultural Engineering by the American Society of Agricultural Engineers in 1980, shortly after testing was moved to a …

Physics, Chapter 33: Magnetic Properties Of Matter, Henry Semat, Robert Katz Jan 1958

Physics, Chapter 33: Magnetic Properties Of Matter, Henry Semat, Robert Katz

Robert Katz Publications

Matter is composed of atoms consisting of positively charged nuclei and negative electrons. These electrons occur in shells, and the periodic nature of chemical properties of atoms as the atomic weight increases is a reflection of the fact that the chemical behavior of an atom depends largely upon the number of electrons in the outermost shell. In some parts of the periodic table (see Table 5 of Appendix A), electrons occupy places in an outer shell before an inner shell is completely filled; it is then observed that a number of different elements have very similar chemical properties. The same …


Physics, Chapter 28: Electrical Conduction In Liquids And Solids, Henry Semat, Robert Katz Jan 1958

Physics, Chapter 28: Electrical Conduction In Liquids And Solids, Henry Semat, Robert Katz

Robert Katz Publications

We have seen that electrical conduction in solids is associated with the drift of free electrons in the solid, a process which will be examined in greater detail in Section 28-4. A similar mechanism may be used to account for the conduction of electricity in liquid metals. In other liquids electricity is conducted by the migration of positive and negative ions through the liquid.


Physics, Chapter 5: Force And Motion, Henry Semat, Robert Katz Jan 1958

Physics, Chapter 5: Force And Motion, Henry Semat, Robert Katz

Robert Katz Publications

All of us have many times had the experience of setting a body in motion. If we analyze any of these experiences, we readily recall that in each case some force was required to start the object moving. In throwing a ball, moving a piece of furniture, or pulling a sled, the force needed to start the object moving is supplied by one's muscular effort as a push or a pull. In more complex cases, such as setting a car or an airplane in motion, the analysis, although more complicated, will also show that a force is required to start …


Physics, Chapter 26: The Electric Current, Henry Semat, Robert Katz Jan 1958

Physics, Chapter 26: The Electric Current, Henry Semat, Robert Katz

Robert Katz Publications

Electricity is the basis of our present highly technical civilization. It is the means whereby energy from various sources is delivered to the consumer in a form suitable for its conversion into the many kinds of energy demanded by him. It is through the intermediary of the electric circuit that energy is transmitted electrically from the primary source, no matter where it is situated, to the ultimate consumer wherever he desires it. A complete electric circuit contains some form of electric generator, which is essentially a device for converting other forms of energy to electrical energy, a set of conductors …


Physics, Chapter 13: Properties Of Matter, Henry Semat, Robert Katz Jan 1958

Physics, Chapter 13: Properties Of Matter, Henry Semat, Robert Katz

Robert Katz Publications

When a system is subjected to external forces, it generally undergoes a change in size or shape or both. We have thus far touched very lightly on such changes; for example, we have considered the change in length of an elastic spring and the change in volume of a gas when such systems were subjected to varying pressures. The changes produced in a system by the action of external forces depend upon the physical properties of the material of which the system is composed. A study of the properties of matter leads to information which is of practical value to …


Physics, Chapter 4: Statics Of A Rigid Body, Henry Semat, Robert Katz Jan 1958

Physics, Chapter 4: Statics Of A Rigid Body, Henry Semat, Robert Katz

Robert Katz Publications

In the preceding chapter we observed that a particle would remain in equilibrium, in a state of rest, or in a state of uniform motion in a straight line when the resultant of all the forces acting on it was equal to zero. This condition for equilibrium was extended to larger bodies under either of two possible conditions: If the forces acting on the body were concurrent, that is, if they were directed toward a single point, the body could be treated as if it were a particle; or if the body moved with uniform translational motion in which every …


Physics, Chapter 3: The Equilibrium Of A Particle, Henry Semat, Robert Katz Jan 1958

Physics, Chapter 3: The Equilibrium Of A Particle, Henry Semat, Robert Katz

Robert Katz Publications

A particle which remains at rest or in uniform motion with respect to its frame of reference is said to be in equilibrium in that frame. Centuries ago it was recognized that the state of rest was a natural state of things, for it was observed that objects set in motion on the surface of the earth tended to come to rest. The maintenance of any horizontal motion on earth was thought to require the continued exercise of a force, hence to be a violent motion, while vertical motion like that of a falling body was thought to be natural …


Physics, Chapter 2: Motion Of A Particle (Kinematics), Henry Semat, Robert Katz Jan 1958

Physics, Chapter 2: Motion Of A Particle (Kinematics), Henry Semat, Robert Katz

Robert Katz Publications

Normally, when we say an object is at rest, we mean that it is at rest with respect to the surface of the earth; when we say a car is moving at a speed of 40 mi/hr, we imply that the motion is taking place at this speed relative to the road. A boat sailing on the river moves with respect to the river's banks, but it also moves with respect to the flowing water in the river. The lift on the wings of an airplane is generated by the motion of the airplane through the air, but it is …


Physics, Chapter 21: Vibrations And Sound, Henry Semat, Robert Katz Jan 1958

Physics, Chapter 21: Vibrations And Sound, Henry Semat, Robert Katz

Robert Katz Publications

There are two aspects of sound: one is the physical aspect which involves the physics of the production, propagation, reception, and detection of sound; the other, which is the sensation of sound as perceived by the individual, depends upon physiological and psychological effects. It is not desirable to separate the two aspects of sound completely, but the main emphasis in this book must necessarily be on the physical aspect. In this chapter we shall consider mostly musical sounds. A vocabulary has been developed to describe the sensation experienced when a musical sound is heard. Such terms as the pitch of …


Physics, Chapter 7: Work And Energy, Henry Semat, Robert Katz Jan 1958

Physics, Chapter 7: Work And Energy, Henry Semat, Robert Katz

Robert Katz Publications

An extremely important concept that has been developed in physics is that of the work done on a body by the action of some external agent which exerts a force on this body and produces motion. For example, whenever someone lifts a body, he does work by exerting a force upward on it and moving it upward. Whenever a steam locomotive pulls a train, a series of processes takes place in the steam engine of the locomotive which enables it to exert a force on the train and move it in the direction of the force. The term work, as …
