Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
Question

Transcribed Image Text:11. Sir Lost-a-Lot dons his armor and sets out from the castle on
his trusty steed (Fig. P12.11). Usually, the drawbridge is low-
ered to a horizontal position so that the end of the bridge
rests on the stone ledge. Unfortunately, Lost-a-Lot's squire
didn't lower the drawbridge far enough and stopped it at
20.0° above the horizontal. The knight and his horse
stop when their combined center of mass is d = 1.00 m from
the end of the bridge. The uniform bridge is l = 8.00 m
long and has mass 2 000 kg. The lift cable is attached to the
bridge 5.00 m from the hinge at the castle end and to a
point on the castle wall h = 12.0 m above the bridge. Lost-a-
Lot's mass combined with his armor and steed is 1 000 kg.
Determine (a) the tension in the cable and (b) the horizon-
tal and (c) the vertical force components acting on the
bridge at the hinge.
