A. Find the current, I, required to establish a flux 0= 2.4x10-4 Wb in the
magnetic circuit of Figure. Here, Area(throughout) = 2x10-4 m², lab = Lef= 0.05 m
laf = lbe = 0.02m, lbc = ldc, and the material is sheet steel.
b. Compare the mmf drop across the air gap to that across the rest of the magnetic
magnetic
circuit. Discuss your results using the value of u for each material.
(NOTICE: find the magnetization curve in page 29 Figure 1.32 in Reference 00
Motor and controlling. The reluctance of sheet steel should be taken into
calculation)

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.
