Q1) The concrete pier P is being lowered by the pulley
and cable arrangement shown. If points A and B
have velocities of 0.4 m/s and 0.2 m/s, respectively,
compute the velocity of P, the velocity of point C for
the instant represented, and the angular velocity of
the pulley.

Q2) The slotted arm pivots about O and maintains the
relation between the motions of sliders A and B and
their control rods. Each small pivoted block is
pinned to its respective slider and is constrained to
b
slide in its rotating slot. Show that the displacement
x is proportional to the reciprocal of y. Then estab-
lish the relation between the velocities VA and vg.
Also, if v, is constant for a short interval of motion,
determine the acceleration of B.
Q3) 16-45. Determine the velocity of rod R for any angle e of
the cam C if the cam rotates with a constant angular
velocity w. The pin connection at O does not cause an
interference with the motion of A on C.
