A string is wrapped around a uniform solid cylinder of radius r, as shown in the figure (Figure 1) . The cylinder can rotate freely about its axis. The loose end of the string is attached to a block. The block and cylinder each have mass m. Note that the positive y direction is downward and counterclockwise torques are positive. Find the magnitude α of the angular acceleration of the cylinder as the block descends. Express your answer in terms...
torque on a cylinder Cylinder drop (2) A uniform cylinder of mass m - 2 kg. radius r = 0. 1 m (and I = 1/2mr^2) has a massless, frictionless string wrapped around the outside, and is subsequently dropped from rest. The cylinder will fall and the string will unwind like a yo-yo. The string will haw some tension T during this process. Find the net force acting on the cylinder (in terms of T if necessary). Find the net...

A bucket of mass m is hanging from the free end of a rope whose other end is wrapped around a drum (radius R, mass M) that can rotate with negligible friction about a stationary horizontal axis. The drum is not a uniform cylinder and has unknown moment of inertia. When you release the bucket from rest, you find that it has a downward acceleration of magnitude (a). What is the tension in the cable between the drum and the...
4:36 # $24 OKO 34% A solid cylinder with mass m and radius r rolls without slipping down an incline that makes a 3B" with the horizontal What is the moment of inertia of the solid cylinder about the center of mass?

I need a step by step on 1 and 2 so I can teach myself. 1. A solid, uniform sphere with a mass of 2.0 kg is rolling from rest down an incline plane from the top of the plane. The incline plane makes an angle of 20° with the horizontal and has a height of 2.0 m. At the bottom of the incline plane, the surface levels out to a frictionless horizontal surface. A spring with a spring constant...
front view side view FT 1 R Ms Pulling the yo-yo [9pt] A non-intuitive motion that combines translation and rotation is pulling a wheel with a string wrapped around it, as shown in the figure above. Depending on what angle the string is pulled, you can obtain three kinds of motion: the yo-yo accelerating in the direction of the applied tension force and winding up, the yo-yo accelerating in the opposite direction of tension and unwinding, and the yo-yo sliding...

Learning Goal: To understand and apply the formula τ=Iα to rigid objects rotating about a fixed axis. To find the acceleration a of a particle of mass m, we use Newton's second law: F⃗ net=ma⃗ , where F⃗ net is the net force acting on the particle. To find the angular acceleration α of a rigid object rotating about a fixed axis, we can use a similar formula: τnet=Iα, where τnet=∑τ is the net torque acting on the object and...
