Question



The wire in the figure carries a current I that is increasing with time at a constant rate. The induced emf in each of the loops is such that


loop A has counterclockwise emf, loop B clockwise emf, and loop C has clockwise emf.
no emf is induced in any loop.
loop A has clockwise emf, loop B has no induced emf, and loop C has counterclockwise emf.
all loops experience counterclockwise emf.

loop A has counterclockwise emf, loop B has no induced emf, and loop C has clockwise emf.

The velocity of point B on the linkage sh Fig. P3.8 is 40 m/s. Find the velocity 0f ^il1 and the angular velocity of link 3.

Explanation / Answer

loop A has clockwise emf, loop B has no induced emf, and loop C has counterclockwise emf
