Termehu Dievskaya VA The dynamics of the task 5 (D5) on the theme "D´Alembert´s Principle":
For the examples in Scheme 1-30 mechanical systems using the principle of D´Alembert, to determine the magnitude of the force F, needed to move cargo at the set acceleration a1 as well as efforts in the cargo rope. Background: load mass m1 and m2 of the drum, the drum radius R2 (at the double drum has also r2), its radius of gyration of P2 (if it is not specified, the body is regarded as a homogeneous cylinder), and the angle and the coefficient of friction f in the table. Unnumbered blocks and rollers considered weightless. Friction on the axes of the drum and blocks neglected.
Solution of the A5 line number 1 and the circuit conditions
Right after the payment you receive a link to the archive with the solution of the problem in theoretical mechanics D5 B1 (Figure 1) in the test book "theoretical mechanics" Dievskaya VA Malyshev IA 2009 for university students.
The task is made in the format word (typed or hand-written decision in a Word), packed to the archive zip (open on any PC).
After checking the solutions I would be very grateful if you leave your positive feedback.
