Question

As a hydraulic cylinder rotates around O, the exposed length L of the piston rod P is controlled by the action of oil pressure in the cylinder. If the cylinder rotates at a constant rate 0- 60 deg/sec and L is decreasing at the constant rate of 150 mm/sec, calculate the magnitudes of the velocity and acceleration A of end B when L-125mm V 375 m 1)

Answer 1

Magnitudes of velocity and acceleration of end B when l = 125 mm

Velocity: 375 +125 = 500 mm rad/s, θ = 0 180 y, =r=-150 mms, v,-re-(500)--523.60 mm/s v = v, t v-V/(-150)' + (523.60), = 544.66 mm /s Acceleration: | =-548.31 mm/s a,-r0+2H-O+2(-150)(--314.16 m a-Ja, t as = V(-548 .31)' + (-314.16), = 631 .93 mm /s
