Rework given Example changing dimension a to 10 ft, dimension b to 15 ft, and the point load to 15 kips.
Example Select the most economical (lightest) structural steel wide-flange section (W shape) for the propped cantilever beam that supports the loads shown in given Figure. Consider moment and shear only. Assume A992 steel (F y =50 ksi). Neglect the weight of the beam. The vertical deflection at support A is zero.

What are the direction and magnitude of the force exerted on an electron located at this distance? I have determined that the direction is toward the nucleus but am unsure of how to derive the magnitude.
Determine the angular momentum of the particle about the point B (0, a, 0).
Electrical energy can be converted to heat energy with an efficiency of 100%, by sending a current through a resistor and using "Joule heating": P = I2 R. Explain how this doesn't violate the 2nd Law, which told us that the efficiency of an engine ..
