A 20.8 foot long board, whose weight is 12.8 lbs, is supported from below on each end. A 164.1 lb person is standing 16.6 ft from the left end. What is the support force ( in pounds) applied to the board from the left side?
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 20.8 foot long board, whose weight is 12.8 lbs, is supported from below on each end. A 164.1 lb person is standing 16.6 ft from the left end. What is the support force ( in pounds) applied to the board from the left side?
Given
Length of board, L = 20.8 ft
Weight of board, W = 12.8 lbs
Weight of person , W1 = 164.1 lbs
Is at d = 16.6 ft from left end
Support force on left end is ,Fl
