  <p>In the crank-slider mechanism shown, arm 2 rotates at a constant CW angular
    velocity of 2.deltadeltadeltadelta rad/s. Arm 2 is 50mm and is pinned at fixed point B and to the
    center of sliding block 1. Slotted arm 4 is pinned to fixed point C and
    contains a pin at D 250mm from C. Pin D is connected to block E by link 5.
    Block E slides freely on a horizontal plane. Assume at the instant under
    consideration link 5 is horizontal, despite that it does not appear so in the drawing.
    Points B and C are vertically aligned, so the mechanism position is completely
    determined by two parameters, the angle of link 2 and the distance down the
    link of points C to 1. If link 4 is 75 degrees from the horizontal and the
    distance from C to 1 is 135mm, determine the horizontal velocity and
    acceleration of block E.</p>
