When the 1 kg ball starts to rotate around the horizontal circular path A with a Constant speed of 1 m/s the rope connecting the ball passes through a pulley (in point C, not shown in the figure), which is fixed to the ceiling. A force F is applied as shown in the figure. If the force F on the cord increases, the ball rises and eventually reaches a new position and rotates around the horizontal circular path B. The...

1) Consider a block of mass M connected through the massless rigid rod to the massless circular track of radius a on a frictionless horizontal table (see the Figure). A particle of mass m is constrained to move on the vertical circular track. The distance between the center of the circular track and the center of mass of the block of mass M is constant and equal to L. Assume that there is no friction between the track and the...

A small block of mass m2 hangs from a massless rope wrapped around the inner cylinder of a pulley with inner radius of R2. The moment of inertia of the entire pulley is I = 4m2(R2)2. Another block m1= m2 is connected to the outer cylinder of the pulley via a horizontal massless rope wrapped around the outer cylinder of the pulley with radius R1=2R2. The coefficient of kinetic friction between the block and the horizontal surface is μk =...
