- Given: AB = 0.1 m , CB = 0.4 m, CD = 0.6 m, AD = 0.8 m For the linkage shown below, CD moves back and forth spinning flywheel AB, link CD is the input link. a.) Find the maximum angle in degrees, that is the angle between the extreme positions by the link CD when the circle AB rotates 360 degrees? b.) Why is the wheel able to rotate fully and not get locked up when CD and AB are inline (collinear)? Where's a real life example where this mechanism may be used?arrow_forwardRefer to the figure below for the mechanism. If link 2 rotates at a speed of 60 revolutions per minute in a counterclockwise direction , find the velocity, using resolution and composition method of: A point connecting link 2 to link 3 A point at the center of link 2 A point at the center of link 3 Of the slider Also, locate all the instantaneous centers.arrow_forwardFor the walking-beam mechanism of Figure P4-9, calculate and plot the xand y components of the position of the coupler point P for one complete revolution of the crank O2A. Hint: Calculate them first with respect to the ground link O204 and then transform them into the global XY coordinate system (i.e., horizontal and vertical in the figure). Scale the figure for any additional information neededarrow_forward
- In the kinematic diagram, the limb dimensions are given below, in the arm slide mechanism, the actuating limb angular position is (theta)θ12 = 600 and the speed of the mechanism is given as (thetadot)θ'12 = 50 rad / s . Do the following operations respectively. Write the Vector Closure Equation into scalar form.arrow_forwardHow would you put this into vector form.arrow_forwardFigure 1 illustrates transformation involving a frame. Construct the transformation matrix of point C relative to point A.arrow_forward
