A solid cylinder, mass of 15 kg, is on a hill that is inclined at a 45 degree angle. If it rolls down the hill without slipping find:

1. The acceleration of the cylinder

2. The force of friction acting on the cylinder

3. The minimum possible coefficient of friction

Explain.

Expert Solution

mg is the weight of the cylinder which is split into its components

Fr is the frictional force

--------------------------

Consider the sold cylinder

Rolling of cylinder is caused due to frictional force

Net Torque =Moment of Inertia * angular accleration

,where moment of inertia of sold cylinder, ,

angular acceleration, and

Torque,

-------

So

------------(1)

------------------

Frictional force =Coefficient of friction * Normal Reaction

--------------(2)

-------

From (1) and (2)

------(3)

====================

Consider the cylinder

Net Force =Mass *acceleration

Put (3) in above equation

A solid cylinder with a mass of 3 kg, a radius of 25 cm, and a length of 40 cm is rolling across a horizontal floor with a linear speed of 12 m/s. The cylinder then comes to a ramp, and, as it is rolling up this ramp without slipping, it is slowing down. When the cylinder finally comes to a stop and begins rolling back down the ramp, how high is it above the floor?

A solid cylinder has a mass of 2.50 kg and a radius of 0.100 m. It is released from rest on a ramp tilted at 8.00° from horizontal, and it rolls without slipping down the ramp until it has moved a vertical distance of 0.350 m. What is the angular speed of the cylinder when it reaches the bottom? What is the magnitude of the angular momentum of the cylinder when it reaches the bottom?

A compost barrel can be considered as a solid cylinder of mass 50.0 kg and radius of r = 30.0 cm, and a length of 0.900 m. It can be turned about the long axis by applying a force to a handle located d = 20.0 cm from the axis of the cylinder. The compost barrel needs to be turned through 250 complete revolutions. Assume you can apply a constant force of F = 10.0 N (always perpendicular to the...

A block of mass m2 = 15 kg on a rough 30°-inclined plane is connected to a 5-kg mass (m1) by a string of negligible mass passing over a pulley that is shaped like a disk. The 2-kg pulley has radius 15 cm and rotates about its symmetry axis of rotation. The string does not slip on the pulley and causes the pulley to rotate about a fixed horizontal axle through its center of mass. When this system is released...

A solid, uniform cylinder with mass 8.25 kg and diameter 10.0 cm is spinning with angular velocity 245 rpm on a thin, frictionless axle that passes along the cylinder axis. You design a simple friction-brake to stop the cylinder by pressing the brake against the outer rim with a normal force. The coefficient of kinetic friction between the brake and rim is 0.344.
