Describe the similarities and differences between
flexural-torsional buckling and
lateral-torsional buckling. What is the coupling mechanism for
each of these buckling modes?
1. Discuss the differences between the Einstein’s Theory of
Relativity and Classical Physics Theory (i.e. Galileo and Newton,
etc.)
2. Discuss the wave-particle duality of light and its
implications. What are possible industrial applications?
With the aid of a sketch, explain what is lateral torsional
buckling of a steel beam, when it might occur, and what a
structural engineer would do about it.
Which law of physics led Einstein to develop the Theory of
Relativity. :
Gravity is always attractive.
Motion is relative.
The speed of light is a constant.
The entropy of the universe always increases.
Modern Physics: Experimental basis for quantum theory +
Atomic models
Use the value for the intensity of sunlight at the surface of
the earth from the previous question. Assume that all the light has
the same frequency, 5 x 1014? Hz.
a. Classical approximation: if the light described above is
incident upon a 1 m2? patch of sodium metal, calculate
the average amount of energy each atom in the surface
receives per second as well as the amount of...
