A 2D plane is divided into two haves. In one half, a constant magnetic field of 3 T points out of the page. In the other the magnetic field is zero. A square wire of side 4 m is half-way into the magnetic field region. It is being pulled out with a speed of 5 m/s. What is the emf enduced in the wire?

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.

If a tank filled with water contains a block and the height of the water above point a within the block is 0.8 meter, what is the pressure at point a?
