Figure P2-10 shows Watt's sun and planet drive that he used in his steam engine. The beam 2 is driven in oscillation by the piston of the engine. The planet gear is fixed rigidly to link 3 and its center is guided in the fixed track 1. The output rotation is taken from the sun gear 4. Sketch a kinematic diagram of this mechanism and determine its DOF. Can it be classified by the Barker scheme? If so, what Barker class and subclass is it?

A scuba diver descends to 40 meters below the surface and has a 10 liter tank that contains air at 9 MPA and 7 C. Assume that the water has a density of 1000kg/m^3 and that atmospheric pressure is 100 KPA. He breathes at 5/ liters/min. How long can h..
At a given temperature, a hypothetical isomorphous A-B alloy of composition 40wt% B - 60wt% A is found to be 66wt% (B) alpha phase and 34wt% liquid phase, L. If the composition of the alpha phase is 13wt% B - 87wt% A, what is the composition of the l..
Water flows through a 2-in.-diameter pipe with a velocity of 15 ft/s as shown in Fig. P8.84. The relative roughness of the pipe is 0.004, and the loss coefficient for the exit is 1.0. Determine the height, h, to which the water rises in the piezom..
