The safe load, L, of a wooden beam of width w, height h, and length l, supported at both ends, varies directly as the product of the width and the square of the height, and inversely as the length. A wooden beam 4 4 inches wide, 9 9 inches high, and 168 168 inches long can hold a load of 5930 5930 pounds. What load would a beam 3 inches wide, 7 inches high, and 120 inches long, of the same material, support? Round your answer to the nearest integer if necessary.
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.
