Two masses are tied to the ends of a rope, and the rope is draped over a pulley. This arrangement is known as "Atwood's machine." Assume the rope and pulley are massless and there is no friction in the pulley. When the masses are of 20.5 kg and 14.7 kg, calculate the magnitude of their acceleration, a, and the tension in the rope, T. Take g = 9.81 m/s2. Use Free Body Diagrams to support your analysis.
2. The pulley (disk) has a radius "R" and a mass "m". The rope does not slip over the pulley, and the pulley spins on a frictionless axle. The coefficient of kinetic friction between block A and the surface is "u. The system is released from rest and block B descends. Block A has a mass "2m" and block B has a mass "m Write out the forces and torque equations. Given [R, m, h, ], Determine: a. The acceleration...
Two blocks are connected by a massless rope that passes over a pulley. The pulley is 12 cm in diameter and has a mass of 2.0 kg. As the pulley turns, friction at the axle exerts a torque of magnitude 0.50 Nm. If the blocks are released from rest, how long does it take the 4.0-kg block to reach the floor? 4.0 kg 1.0 m Answer: 2.0 kg t = 1.1 s
The two blocks in the figure(Figure 1) are connected by a massless rope that passes over a pulley. The pulley is 14 cm in diameter and has a mass of 3.0 kg As the pulley turns, friction at the axle exerts a torque of magnitude 0.53 N.m. Part A If the blocks are released from rest, how long does it take the 4.0 kg block to reach the floor?
The two blocks in the figure Figure 1) are connected by a massless rope that passes over a pulley. The pulley is 14 cm In diameter and has a mass of 2.1 kg. As the pulley turns, friction at the axle exerts a torque of magnitude 0.52 N·m. Part A If the blocks are released from rest, how long does it take the 4.0 kg block to reach the floor?

A block with mass mb = 1.9 kg is connected by a rope
across a 50-cm-diameter, 2.0 kg pulley, as shown in (Figure 1).
There is no friction in the axle, but there is friction between the
rope and the pulley; the rope doesn't slip. The weight is
accelerating upward at 1.2 m/s2. What is the tension in the rope on
the right side of the pulley?
As shown in Figure 3(a), a wooden block B with mass mg 2.4 kg on a rough inclined plane is connected to a massless spring (k 160 N/m) by a massless cord passing over a pulley P of radius R 0.25 m and mass M, 0.60 kg. The angle of the inclined plane is 0 37 and the coefficients of static and kinetic frictions are g 0.35 and A 0.30 respectively The frictional force at the axle of the pulley...
In the figure, two 6.20 kg blocks are connected by a massless string over a pulley of radius 2.40 cm and rotational inertia of 7.40 Times 10^-1 kg m^2. The string does not slip on the pulley; and there is no friction between the table and the sliding block; the pulley's axis is frictionless. When this system is released from rest the pulley turns through 1.30 rad in 91.0 ms and the acceleration of the blocks is constant. What are...
By means of a rope whose mass is negligible, two blocks are suspended over a pulley, as the drawing shows, with m1 = 10.7 kg and m2 = 46.0 kg. The pulley can be treated as a uniform, solid, cylindrical disk. The downward acceleration of the 46.0-kg block is observed to be exactly one-half the acceleration due to gravity. Noting that the tension in the rope is not the same on each side of the pulley, find the mass of...
