Question

Figure 2 below shows a mechanism in which OA QC = 100 mm, AB OB = 300 mm and CD = 250 mm

Figure 2 below shows a mechanism in which OA QC = 100 mm, AB OB = 300 mm and CD = 250 mm. The crank OA rotates at 150 r.p.m in the clockwise direction.

2.1 the velocity of the slider at D

2.2 the least absolute velocity of a point on link AB

2.3 the angular velocities of links AB and QB

2.4 the rubbing velocity at the pin B which is 40 mm in diameter

2.5 the force exerted by the piston if the system is driven by a 5 kW motor with a 90% efficiency

Answer #2

.The angular velocity of link 2 of the mechanism shown in Figure 1 is ω2 and the angular acceleration is α2 at the instant being considered. Determine the linear acceleration of point Fand the angular acceleration of link 5. Take: EF = 65 mm, CD = 26 mm, AB = 14 mm, BC = 55 mm, VC = 435 mm/s, VC/B = 197.5 mm/s and VF/E = 284 mm/s. W2=44 CCW a2=129CW θ2=22 Φ1=33 Φ2=27 AA=2.5 BB=68 CC=48

Answer

theory of machines

In a mechanism as shown in Fig. 8.40, the crankOA is 100 mm long and rotates in a clockwisedirection at a speed of 100 r.p.m. The straightrod BCD rocks on a fixed point at C. The linksBC and CD are each 200 mm long and the linkAB is 300 mm long. The slider E, which isdriven by the rod DE is 250 mm long. Find thevelocity and acceleration of E.[ Ans. 1.26 m/s; 10.5 m/s2]
