The elements of a switching device are shown. If the vertical control rod has a downward velocity v = 3.2 ft/sec and an upward acceleration a = 1.9 ft/sec2 when the device is in the position shown, determine the magnitude of the acceleration of point A. Roller C is in continuous contact with the inclined surface. A04" 350 18 87.8284 Answer: aA = ft/sec2

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%
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.

(10%) Problem 10: Modem roller coasters have vertical loops like the one shown in the figure. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. Otheexpertta.com * 33% Part (a) What is the speed of the roller coaster in m/s at the top of the loop if the radius of...
