A uniform ladder is 10 m long and weighs 200 N. , the ladder leans against a vertical, frictionless wall at height h = 8.0 m above the ground. A horizontal force is applied to the ladder at distance d = 2.0 m from its base (measured along the ladder). (a) If force magnitude F = 50 N, what is the force of the ground on the ladder, in unit-vector notation? (b) If F = 150 N, what is the force of the ground on the ladder, also in unit-vector notation? (c) Suppose the coefficient of static friction between the ladder and the ground is 0.38; for what minimum value of the force magnitude F will the base of the ladder just barely start to move toward the wall?
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.
A uniform ladder is 10 m
long and weighs 200 N. , the ladder leans against
a vertical, frictionless wall at height
h = 8.0 m above the ground. A
horizontal force is applied to the
ladder at distance d = 2.0 m from
its base (measured along the ladder).
(a) If force magnitude F = 50
N, what is the force of the ground
on the ladder, in unit-vector notation?
(b) If F = 150 N, what is the
force of the ground on the ladder,
also in unit-vector notation? (c) Suppose the coefficient of static
friction between the ladder and the ground is 0.38; for what minimum
value of the force magnitude F will the base of the ladder
just barely start to move toward the wall?
