The mechanism below consists of a rigid bar and a box pinned to it at . a spring connects a disk of radius, , that rolls without slip in the box. the distance from the pivot point to the cenab b bo r b 0 0 ter of the disk is ( where is the undeformed spring length and is its change in length. a) determine the component of the acceleration in the direction of point , , in terms of , , and o l x ) l x x o x + (and their derivatives). the angles and can be large but the spring restricts and thus to be small, b) linearize your result from a) assuming , , and are small, c) check your resullt for b) b x x x y assumning small displacements initially.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
