PROBLEM 15.90 (Continued)
PROBLEM 15.91
The disk is released from rest and rolls down the incline.
Knowing that the speed of A is 1.2 m/s when
θ
= 0°, determine
at that instant (a) the angular velocity of the rod, (b) the velocity
of B. Only portions of the two tracks are shown.
PROBLEM 15.92
The pin at B is attached to member ABD and can slide freely along the slot
cut in the fixed plate. Knowing that at the instant shown the angular velocity
of arm DE is 3 rad/s clockwise, determine (a) the angular velocity of
member ABD, (b) the velocity of point A.
PROBLEM 15.92 (Continued)
PROBLEM 15.93
Two identical rods ABF and DBE are connected by a pin at B. Knowing
that at the instant shown the velocity of point D is 200 mm/s upward,
determine the velocity of (a) point E, (b) point F.
PROBLEM 15.93 (Continued)
PROBLEM 15.94
Arm ABD is connected by pins to a collar at B and to crank DE.
Knowing that the velocity of collar B is 16 in./s upward, determine
(a) the angular velocity of arm ABD, (b) the velocity of point A.
PROBLEM 15.95
Two 25-in. rods are pin-connected at D as shown. Knowing that B
moves to the left with a constant velocity of 24 in./s, determine at
the instant shown (a) the angular velocity of each rod, (b) the
velocity of E.
PROBLEM 15.95 (Continued)
PROBLEM 15.96
Two rods ABD and DE are connected to three collars as shown. Knowing
that the angular velocity of ABD is 5 rad/s clockwise, determine at the
instant shown (a) the angular velocity of DE, (b) the velocity of collar E.
