An engine crankshaft drives a reciprocating pump through a mechanism, as shown in Figure 1.0 (a). The crank OA rotates in the counter-clockwise direction at 150 rpm. The diameter of the pump piston at F is 180 mm and OA = 175 mm, AB = 650 mm, CD = 160 mm, and DE = 600 mm. Determine: a) The velocity of cross head E (5 Marks) b) The rubbing velocities at pins A, B, C, and D having (15 diameters of 40 mm each Marks) c) The torque required at the crank to overcome a pressure (5 Marks) of 0.35 MPa at the pump piston at F. -Bell crank lover 300 mm 90° 600 mm 100 mm (c) Velocity diagram A () Configuration diagram (b) Angular velocity Figure 1.0
