Summit the followings:

(1) In-class submission: your derivation of the solution and the plots for the result on paper with this page (pledge signed) as the cover page

(2) On-line submission: your Matlab script program.

For the
reversed slider-crack linkage shown in the following figure, (a) derive the
position, velocity, and acceleration equations _{4},*r*_{4},_{4},*r*&_{4},_{4},&*r*&_{4} as well as the shake force
equations. Then (b) code a MATLAB script to calculate and plot _{4},*r*_{4},_{4},*r*&_{4},_{4},&*r*&_{4} as well as the crank torque T_{2 }and
the reaction force on the contact surface of the slider 3 and link 4 for one
rotation of the driver crank.
