Termehu Dievskaya VA Static assignment 4 (C4) on the theme "The system forces the presence of friction":
For in Scheme 1-30 mechanisms located in the vertical plane to determine the value of the force F of the conditions of equilibrium mechanisms. The mechanism consists of a homogeneous thin web length L AB = 4m weight G = 15 kN and two sliders weightless A and B, which can move along guides. At the core of acting couple with moment M = 20 kN * m. The friction of the slider B is absent, the friction coefficient of the slider on the guide A f = 0.4. Slide dimensions neglected.
Solution of the C4 circuit 6

Right after the payment you receive a link to the archive with the solution of the problem in theoretical mechanics C4 B6 (Figure 6) 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.
