    Lecture Problem 2) • Use the analytical approach to design a crank rocker for a rocker amplitude of =60 (CCW). Link r 2 is the crank and r is the rocker. At the position 1 the output rocker link has an angle of 90 relatively to the ground link r 1 as shown in the figure. The transmission angle at the position 2 is 90 . Complete the design of the 4-bar.

Another form of crusher feed blockage results from a large boulder that cannot enter the feed as shown in Figure 9. Occasionally the boulder can be repositioned in the feed system so that a smaller dimension of the boulder can be nipped by the crusher mechanism.

    Rocker Any link which does not revolve is called a rocker. Crank-rocker mechanism In a four bar linkage if the shorter side link revolves and the other one rocks (i.e. oscillates) it is called a crank-rocker mechanism. Double-crank mechanism In a four bar linkage if both of the side links revolve it is called a double-crank mechanism.
