The elements of a switching device are shown. If the vertical control rod has a downward velocity v = 2.1 ft/sec when the device is in the position shown, determine the corresponding speed of point A. Roller C is in continuous contact with the inclined surface. AO A" 410 190 15.84518 5.84518 Answer: VA = ft/sec the tolerance is +/-2%
The elements of a switching device are shown. If the vertical control rod has a downward velocity v of 2.8 ft/sec when 9 = 70° and if roller A is in continuous contact with the horizontal surface, determine the magnitude of the velocity of C for this instant. 6.7" 6.7" Answer: Vc = ft/sec the tolerance is +/-2%
Problem 4: The elements of a switching device are shown below. The vertical control rod has a downward velocity of v0.6 and an upward acceleration of a0.36 th instant shown.r roller C remains in continuous contact with the inclined surface, determine the velocity and acceleration of point A at the instant shown Dynamics, Meriam, Problem 5.134 Answer: ta--0.41 i-1311 m , ?,-+ 12.48i + 4.06j s 75 30° 75 15°
I got vc = 3.646 and w = 12.93. w is magnitude of angular velocity. This was correct. I got ac = -134.31 and a(magnitude of angular acc) = -277.37. This was correct. I’m having trouble finding the acceleration of point A. i got the x part right but not the y part. I got aA = 127.75i + 43.8j but the 43.8j part is wrong. hapter 5, Problem 5/108 Multistep has a downward velocity v-3.0h/sec and an upward acceleration...
The bar shown remains in contact with the vertical wal surface A and with edge B. At the instant shown, A is moving upward with a constant velocity of 6 ft/s. Determine (a) the angular velocity in rad/s and (b) the angular acceleration in rad/s/s of the bar at the instant y 8 ft. Assume w 11 ft.
