A ferromagnetic sphere of radius b is magnetized uniformly with a magnetization M = ˆzM0. Determine the equivalent magnetization current densities (volume and surface) inside the magnet and at its surface, and calculate the magnetic field intensity and flux density at the center of the sphere. Take-aways: This is very similar to the permanent electric polarization problem from a previous homework. Does anyone remember Buckyballs?

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

What are the major differences between injection molding and extrusion?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
