WARNING : THIS IS TOUGH:


If someone does'nt have a liking towards really tough ones, plz. take a walkover...

The dual-wedge shown in the figure is MASSLESS. All surfaces are smooth.
Find the min ratio m1/m2 so that the ball m2 'starts climbing up the wedge'..ie. it starts moving up the incline in the direction shown.

    soln. is quite long...here's some hints:

    1)assume relative accns. of the two balls parallel to the inclines..

    2)assume some accn. A of the wedge..

    3)assume normal reactions on the two balls: N1 and N2.

    finally, u must use N1=N2...why??
