Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

HW3. Due date: Mid night of 4 March 2021
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,

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
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 va 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 0 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.
