Solution of problem D3 Option 20 (task 1, 2) Dievsky VA

Termeh Dievsky V.A. offers two problems in Dynamics 3 (D3) related to the theorem on the change of kinetic energy.

Task 1: It is necessary to determine the angular acceleration (options 4, 6, 7, 9, 11, 18, 25, 26, 28) or linear acceleration (other options) of body 1, using the theorem on the change in kinetic energy in differential form for those shown in the diagrams 1-30 mechanical systems. The threads should be considered weightless and inextensible. For calculations, it is necessary to know the masses of the bodies (t), radii (R and r) and radius of gyration (r; if it is not specified, then the body is considered a homogeneous cylinder). If there is friction, then the coefficients of sliding friction (f) and rolling friction (fк) are indicated.

Task 2: It is necessary to determine the angular speed (options 4, 6, 7, 9, 11, 18, 25, 26, 28) or linear speed (other options) of body 1 after its given movement Fi1 = 2pi rad or S1 = 2 m. Movement begins from a state of rest. To solve the problem, it is necessary to use the theorem on the change in kinetic energy in integral form for the mechanical systems shown in diagrams 1-30.

The solution to problem D3 for scheme No. 20 must be completed in accordance with the tasks indicated above.

Product description:

You are purchasing the solution to two tasks of problem D3 scheme No. 20 from the collection of tasks “Theoretical Mechanics” Dievsky V.A., Malysheva I.A. 2009 for university students.

The first task requires determining the angular acceleration (for options 4, 6, 7, 9, 11, 18, 25, 26, 28) or linear acceleration (for other options) of body 1 based on the theorem on the change in kinetic energy in differential form. The assignment contains diagrams of mechanical systems indicating the masses of bodies, radii, radii of inertia (if they are not indicated, the bodies are considered homogeneous cylinders), coefficients of sliding and rolling friction, as well as threads that are weightless and inextensible.

The second task requires determining the angular velocity (for options 4, 6, 7, 9, 11, 18, 25, 26, 28) or linear speed (for other options) of body 1 after its given movement, equal to Fi1 = 2pi rad or S1 = 2 m. Movement begins from a state of rest. To solve the problem, it is necessary to use the theorem on the change in kinetic energy in integral form.

Solutions to problems are provided in Word format (handwritten solution or typed in Word) and packaged in a zip archive that can be opened on any PC. After checking the solution, the author will be very grateful if you leave positive feedback.
