End A of the bar AB rests on a frictionless horizontal surface, and end B is hinged. A horizontal force F of magnitude 102 N is exerted on end A. Ignore the weight of the bar. What are the horizontal and vertical components of the force exerted by the bar on the hinge at B?
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.
Please answer these 2 complete solutionssssssss and correct only.....
LETTER B PROB....
End A of the bar AB rests on a frictionless horizontal surface, and end B is hinged. A horizontal force ?⃗ F→ of magnitude 102 N is exerted on end A. Ignore the weight of the bar. What are the horizontal and vertical components of the force exerted by the
bar on the hinge at B?
LETTER D PROB...
A 6.00-m-long, uniform beam is hanging from a point 1.00 m to the right of its center. The beam weighs 140 N and makes an angle of 30.0° with the vertical. At the right-hand end of the beam a 100.0 N weight is hung; an unknown weight w hangs at the left end. If the system is in equilibrium, what is w? You can ignore the thickness of the beam. (b) If the beam makes, instead, an angle of 45.0° with the vertical, what is w?
