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 = 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 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...
CLASS ID#: (3) GIVEN: (35 PTS) A slender 9-Ib rod AC can rotate in a vertical plane about a pivot at B. Attached to the rod at C is a spring with a stiffness of k=30 lb/ft and an unstretched length 6 inches. The rod is released from rest in the position shown. FIND: (A) (-10 Pts) The ANGULAR VELOCITY (c) of the rod AC after it has rotated through 90° (B) (-10 pts) The corresponding REACTION at the pivot...

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
