The crankshaft of Fig. 10.33 has four equal cranks at 90° and spaced 100 mm apart. Each crank is equivalent to 18 N at a radial distance or 50 mm. Calculate the bearing reactions due to the inertia forces if the shaft is run at 3000 rpm. Balance this system with two weights WA and WB in the planes of W1 and W2, respectively, and at a radial distance of 50 mm. Determine WA and WB, and show their positions.

Shown below are six figures in which a student is holding a meter stick horizontally. In these figures, the length of the meter stick is denoted as L. All of the meter sticks are identical, but the objects hanging from the sticks vary in mass and ..
A piston cylinder holds air at 80 F and 15 psi. During an adiabatic process the pressure is increased to 165 psi and the entropy generated is 0.15 BTU/lb-R. Determine the isentropic efficiency for this process.
