A construction worker attempts to lift a uniform beam off the floor and raise it to a vertical position. The beam is 2.50 m long and weighs 500 N. At a certain instant the worker holds the beam momentarily at rest with one end at distance d =1.50 m above the floor, , by exerting a force on the beam, perpendicular to the beam. (a) What is the magnitude P? (b) What is the magnitude of the (net) force of the floor on the beam? (c) What is the minimum value the coefficient of static friction between beam and floor can have in order for the beam not to slip at this instant?
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 construction worker attempts
to lift a uniform beam off the
floor and raise it to a vertical position.
The beam is 2.50 m long and
weighs 500 N. At a certain instant the
worker holds the beam momentarily
at rest with one end at distance d =1.50 m above the floor, , by exerting a force on
the beam, perpendicular to the
beam. (a) What is the magnitude P?
(b) What is the magnitude of the (net) force of the floor on the
beam? (c) What is the minimum value the coefficient of static
friction between beam and floor can have in order for the beam
not to slip at this instant?
