Asuperconducting solenoid is to be designed to have an interior field of 7.171 t with a maximum current of 1000 a. the permeability of free space is 1.25664 × 10−6 t · m/a. how many windings are required on a 1- meter solenoid length?

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
