Bar AB slides, drawing the ends of the horizontal and inclined plane. For any value of the angle in degrees between the bar and the horizontal plane velocities modules its ends will be the same if the angle β = 60 °.

Right after the payment you will receive a link to a zip archive with the solution of the problem 9.6.5 (Chapter 2 - Kinematics, theme - 9.6: Determination of velocity using the instantaneous velocity center) in theoretical mechanics from the collection of short tasks Kep OE, JA Viba, OP Grapis, JA Svetinysh et al.
