What will happen to the pressure difference across the rheostat? Explain. [3] Hint: calculate the pressure difference across the rheostat before and after the rheostat changes. Be sure to use the correct obstacle and flow when doing this!

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.
