A uniform solid cylinder of mass 10 kg can rotate about a frictionless axle through its center O, as shown in the cross-sectional view in the figure. A rope wrapped around the outer radius R1 = 1.0 m exerts a force of magnitude F1 = 5.0 N to the right. A second rope wrapped around another section of radius R2 = 0.50 m exerts a force of magnitude F2 = 6.0 N downward. a)What is the angular acceleration of the cylinder?

1.) A uniform solid cylinder of mass 10 kg can rotate about a frictionless axle through its center O, as shown in the cross-sectional view in the figure. A rope wrapped around the outer radius R1 = 1.0 m exerts a force of magnitude F1 = 5.0 N to the right. A second rope wrapped around another section of radius R2 = 0.50 m exerts a force of magnitude F2 = 6.0 N downward.
a)What is the angular acceleration of the cylinder?
b) How many radians does the cylinder rotate through in the first 5.0 seconds, if it starts from rest?
Transcribed Image Text:The image depicts a diagram of a mechanical system involving two concentric circles with forces acting upon them. Here's a detailed explanation of the elements in the diagram:
- **O**: This point represents the center of the circles.
- **R1 and R2**: These are radii of the circles. \( R_1 \) is the radius of the outer circle and \( R_2 \) is the radius of the inner circle.
- **F1 and F2**: These are the forces acting on the system.
- \( F_1 \) is acting horizontally to the right along the tangent of the outer circle.
- \( F_2 \) is acting vertically downward along the tangent of the inner circle.
This system could illustrate principles of torque or rotational dynamics, where the forces \( F_1 \) and \( F_2 \) create torques about the center \( O \). The effectiveness of these forces in causing rotation would depend on the magnitudes of the forces as well as the distances \( R_1 \) and \( R_2 \) from the center to the points of force application.
Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
